You can install Akimbot in ESF and if you host a game you won't have all the attacks, so I doubt you can host online games that others can join, but if you join an online game all will be fine. This should be fixed in future updates.
Also, you might want different "Evil" skins for the Good vs. Evil battles, as the current ones are hard to spot. One pack is here:
Evil Skins
Or
Evil Pack
I can't speak to their usefullness or which is better as I just DLed them right now.
