With how you worded this, I wouldn't be surprised if Team Meat ignored your post (or mine) entirely.  However, just looking at my Vita and its controls/screen size/quality, I really would love to be able to play SMB on it, even if there were only one world and character.  The speakers could really bring out SMB's awesome sound effects and even more awesome soundtrack, while the large colorful screen could make the levels very visually appealing and easy to effectively navigate for a handheld.
