I for one vote for some actual RTS gameplay to go with the Warcraft/Starcraft theme. Your materials could be chicks, ammo and booze which would be used to buy troops and upgrade buildings. At the end of each mission you would win a reward chick that you can either choose to keep in your personal harem or give her to your men for an increase in resources during the next mission. I have a tendency to underestimate the difficulty of projects but I don't see this being too bad since you already have a strong framework set up with vanilla BoneCraft. In fact if the mod tools will allow the user to place objects in the 3d space easily then I don't see why it couldn't be made as a mod.
