Assist Trophies into Playable Characters

Which Assist Characters from Brawl would you like to see as a playable character in SSB4?
Here are my choices:

Excitebiker
Little Mac
Waluigi

Little Mac and Samurai Goroh.

Some assistants who were subcharacters are not the numebr 2/3 of their own game (Waluigi, Hammer bros etc), so they don't seem to have the chance. They were put in mostly because of their special attack abilitites, and some of which don't really fit in playability.

Little Mac or Saki who are the protagonists might have a bigger chance.
