Well... It works.
Everyone always has Speed Shoes, which makes them extremely hard to control (not to mention the jingle doesn't stop when getting actual Speed Shoes.)
Invincibility (from a monitor) wears off once you do a trick.
And the Speed Twok could be set to spin, but maybe I'm just being picky.
But the idea of characters being "canonically accurate" is actually pretty neat, keep it up.
