No because REALGTA 3 modifies the main.scm file and so does MTA.
Also its not good to mess with the collision and models because it would generate too many errors.
Having the server dowload the appropriate mods to match everyone and having the server check everyones game to see what mods they mods they have would be a very hard thing to do I would think. They would have to make an entirely new program to do that.
