As much as I want to say yes, no. Certainly not this go around, at any rate.Srb2 wiki says that you can now add two WADs with custom textures to the game at the same time without them canceling each other out. Does that mean custom textures (and maybe other things like music?) will be usable in multiplayer divisions?
Actually might make something for July/August, instead.
EDIT: Except if I really have the time to do something for May/June.
