Mod requests (orders).

Hello, I have a couple of questions for you:

1. Is it possible to change the models of - Catapults, Tents, Supply Wagons, and Ballistae?

2. Can we create unique Ballistae, Tents, Catapults, and Supply Wagons for each faction?

3. Is anyone willing to help with the implementation of this mod? I am ready to take on the redesign of these devices, if it is possible at all.
