No, because ONLY the bottom slot can have the jackpot.

You have plenty of +Atk from your Grid already, so I personally prefer +Def and Affliction.

Offensive wise, having lots of +combo is really good for you though. The problem is, actually finding Accessories with two Double/Triple is extremely rare.
