Thanks for clearing that up about transforming mechs. Another question, would a Mechwarrior style slow moving mech with heavy cannons and artillery be approriate for this rp? Or would that focus be on faster, more mobile mechs?

As for enemy character sheets I would say keep them a mystery until we encounter in-game. Perhaps after we deal with them you post their sheet, sort of like the characters analyzed the battle data.
