I don't own Heroes III or AoW:SM.

What you ask, and much more, can be done with mods. Automating the process of downloading and enabling the mod would make using mods in multiplayer games much easier. Also, adding mod auto-managment would theoretically fix all spell and item cost and unit issues, and wouldn't need more and more things to be added to the game setup. Mod automatization would enable us to do more, with less work on Illwinter's side.
