Great to see this thread.
I've started working on a mod, by changing the sound files with Sample Editor 1.6. Here you can see the results so far (I know it's not 100% accurate) and download it if you want to try: [

What I tried to do with no success is to modify the car power to match Formula E (top speed of Renault Spark is 225 kph). Using the physics editor I can change the BHP and gear ratio, but the cars still remain "too powerful" and cannot reach the top gear at the same time.
The most challenging part will be the car modeling and of course the tracks. But I'm still an "amateur" modder to be able to do that. I could do the textures, but I think it's better to have the proper 3D model first.
So count with me, I think we can do a joint effort to make this happen.
