It sounds like fun, but the pitfalls you list worry me. In particular, what if there is a flaw in a mod upgrade that accidentally boosts a unit far out of proportion of what it should be. And then a player invests thousands of gold in them thinking it is a good deal. But when placed in combat the other players complain, the bug is noticed, and then what? Do you undermine that players gold investment?
