Street Fighter and Sesame Street? Mario and Sesame Street worked just fine, so sure, why the hell not.
These Sesame Street x Street Fighter designs are available on redbubble, where you can get them as shirts, hoodies or, if you're a little short on cash, $US2.50 stickers.
Shame they're limited to one design per item! Something with all of them together in one shot would be great.
