A Mario/Nintendo Universe movie could be done successfully, though probably not in the way you guys are thinking.
Make a character from the "real world" the main character who goes into the world of games.
It's basically the same concept as The LEGO Movie and Wreck It Ralph, both of which are huge blockbusters.
If you can make a hit movie based around LEGO blocks, I don't see why a similar take on the video game world couldn't work. Wreck It Ralph did it, but Nintendo should just pool all their characters (and maybe get some third party ones) into one movie.
