I really think this would be a BAD idea, Civ based combat is too detailed already, I generally think combat should be more abstract.
While this type of thing Could be fun, it wouldn't fit well with a game of Civ.
If you stripped down the other (non combat) parts to make civ like an RTS game generator, then it would be a fun game, but not the direction I would like to see in Civ V (probably good for Civ Rev 2 or something like that)
