This wouldn't work with perfect balance, plus your first set of skills you can use in any stance, you only get the added effects if you are in the proper stance for them though.

It would, sort of. The only issue would be starting the combo chain over without going all the way through. A game that does something sort of like this is Aion, where combo chains can vary even on the same class. But that game lets you choose which is the default for the chain.
