Sure - though Christmas is still 8 months away and there's other holidays before that. I usually implement things when we're closer to the respective holidays. It's not even summer yet. ;3
As for stats, I don't like % changes to spells much. If spells are too weak, the % should be on abilities everyone can get, if they're not, then a % change can be quite overpowering and make that item "mandatory" and "best in slot" for a long long long time to come, something I would definitely avoid.
