1st Stage. Would be "misc" characters where everyone can show up as anyone they can think up
2nd Stage. "TV" where they would have to be characters from TV shows.
3rd Stage. "Famous rides" where people would recreate the GTA versions of movie cars and the characters that drove them.
Each stage would have a "best of" competition for who best recreated their character.
The obvious meet locations would places like the vinewood sign, the Chinese theater, and the studio lot.
There would also be missions at each meet point. I was thinking Capture/DM/Race that recreate movie scenes or have a goal that follows a movie plot ("Smokey and the bandit" themed capture or a race that recreates "Vanishing Point" etc etc)
INPUT FROM BobMendez - Setting up a stunt scene from a movie or replicate anything from any movie
