Dude, you could do something like this as a test for a future project. Changes are substantial and the system in question could be used as a basis for a stand-alone game.
Needless to say, because it does sound more complex, it may not be to everyone's tastes. But I think there are enough people who think that the current combat system is flawed enough for them to try something fresh and with a promise for balance.
I suspect the above would happen at some point in the future, though of course... when that would actually happen is not really on the table yet.
Merely speaking from the perspective of a bystander who gets to discuss a lot of the changes here...
