I wouldn't guarantee that it would work correctly, there's several hacks going on that are reading/writing to specific memory addresses in the game, so if for some reason the rfactor exe is different, then it might not work.
Honestly, I don't think creating anything else for the rFactor mod is worth it right now. I feel that the new game I'm working on will be ready enough to replace it sometime in 2018. I plan to have an update to the beta version ready prior to Christmas for you guys to play with. Then, next year, I will start looking into selling the new game via Steam.
