First off, your Batman/Mario is hilarious and nicely done. Very creative and a breath of fresh air.
The Mario/Deadpool sounds promising, since anything with Deadpool always has me giggling like a schoolgirl. However, the pic doesn't work for me, so I can't really judge anything, but like I said, that's an ace idea.
