Fixes for SHAR

One day I was thinking about fixing SHAR by adding some unused vehicles into game because they were planned and changing few other things into game. Here is what I want to "fix" about SHAR (inspiration came from tcrf.net/The_Simpsons:_Hit_%26_Run as well as some ideas since I was young). The mod will not change the core gameplay, it only changes a few things I consider that should have been in the final game. List may or may not be complete but here is what I want to change as for now:

-Level 1: Modify traffic. Now Sedan A will appear on the traffic. It replaces the Pickup Truck that can be found on levels 3 & 6 again.
-Level 2: Modify Mission 7 Cell-Outs to use all 4 variants of Cell Phone Car instead of just the first variant.
-Level 3: Modify Lisa - Cool and Donut Truck to cost 200 coins instead of 250. In the original game, two clothes and two vehicles cost 250 coins, possibly a developer mistake.
-Level 3: Modify traffic. Now Ice Cream Truck will appear on traffic. It replaces the Pickup Truck that can be found on level 6 again.
-Level 4: Modify traffic. Now Station Wagon will appear on traffic. It replaces the SUV that can be found on level 5 again.
-Level 6: Modify Police car that chases you during Hit & Run to be Chase Sedan, as it was planned.
-Misc: Add proper texts to a couple of vehicles like Bonestorm Truck, Glass Truck and Red Brick Car. Also distinguish Sedans (Moe's Sedan and Skinner's Sedan).
-Misc: Modify all 4 variants of Cell Phone Car to no longer make the player character invisible. Instead, the character will be scaled accordingly as other vehicles do.
-Misc: Reduce the Hit Points of Nonuplets' Minivan. Before it was 99.0, now it will be 2.0.
-Misc: Modify All Cars and Play As Any Character cheats. Rearrange the order of cars and characters, add missing NPCs when cycling through characters.

Notes for each change:
-I changed the traffic because I didn't like how some of the cars such as Pickup Truck and Compact Car appear in 3 different levels, yet Sedan A and Station Wagon don't appear at all. Well, not anymore! Now you will see them on the road. They were originally planned to appear on level 1 and I wanted to place them in level 1 but I reminded that Minivan appears once, so I found more fitting if I put Sedan A into level 1, while I put Station Wagon in level 4 and replace one of the traffic cars from here. Same goes to the unused Ice Cream Truck. Although it was probably meant for first level as well, I thought it would fit better in level 3 because it's the only level (not counting level 7) that has only a single "different" vehicle (Fish Van), while the rest levels have at least 2 different vehicles (School Bus and Glass Truck, Taxis, etc).
-For the same reason that the other cars went unused, I decided to modify L2M7 to use all 4 variants of Cell Phone Car as originally planned.
-I am sure that Lisa - Cool and Donut Truck were meant to cost 200 coins instead of 250. Just look at every level, all cars and clothes have different prices. In this case of level 3, two of the clothes and two of the cars have the same price.
-I am also sure that the Chase Sedan was originally meant to chase you at Level 6 in Hit & Run. I also read a similar topic some time ago but I had this idea since many years ago, considering it's another Police vehicle.
-Adding proper texts to vehicles, so that things look a bit nicer and also distinguishing between the 2 sedans. I found it weird that two of cars have the same name. I know that the Red & Black Ferrini have their own name: Ferrini - Red and Ferrini - Black.
-When I got to drive the cell phone cars the first time (about 10 years ago using Lucas Tweak, good times), I found it weird that they make the player invisible and they are the only cars that do that.
-I found out a couple of months ago when playing around with All Cars cheat, that for some reason the Nonuplets' Minivan doesn't get destroyed. It takes about 10 minutes to destroy the car, with the help of jumping car cheat and intentionally crashing it into walls. I think it must be a typo because no car in the game can be that strong. Even the Monster Truck from level 5 isn't that strong.
-The order of cars at phone booth (when using all cars cheat) and the character cycling order could be much better. There are also a couple of NPCs that don't appear at all when cycling through when using the all characters cheat. I hope there is a way to change these cheats.

How does that idea sound? I would like to know what you guys think, so I can start working on this mod in a couple of weeks/months (when I finish with exams at college). Some of the changes are easy to do, others may require help and/or may not be possible (such as changing how cheats work). I would also like to know how to compile the mod, so I can turn the mod into a nice lmlm file.

Great idea man! Hope you can make it a reality!

Thanks man! I will start making it in a few weeks/months.

December 2018 EDIT: Mod has been cancelled long ago in 2016! The reason is that I'm not good at modding (some of the things I could easily change such as making the player visible in Cell Phone Cars and changing the traffic vehicles) but it wasn't worth in the end and I highly recommend instead to check out this topic created by MACCA which does similar (and better) fixes:
