Here is a feat I allowed into my game. I hope I didn't make too large a mistake.
Greater Counterspell
You can counterspell effectively.
Requisite: Improved Counterspell
Benefit: If you have not acted in this round yet, and you succesfully identify someone casting a spell, you may counterspell it even though it isn't your turn. Resolve the counterspelling as usual. Your place in the round's sequence doesn't change, and when your turn arrives you may only make a move (equivalent) action.
