I think this would work rules-wise, but I'm not 100% sure.

Buyback is payed as you cast the spell, same with kicker. You can't wait to see whether or not your opponent wants to counter the spell before choosing whether or not to pay buyback/kicker. An easy fix, just remove "on the stack" from the card text.
