I know of a method for hosting this. If this is something people would want, I can build something and put out a save.
The only addons I would legitimately need would be the airliner, VCE, Slayer and any basic slayer events/bricks. It would be handy to have something along the lines of terrain bricks so that there could be actual terrain and a map, but it wouldn't be fully necessary. Outside of that anything extra would be up to the host (ex; hatmod, brick textures, advanced chat, etc)
