Toad could easily be changed to Toadsworth with a little editing.
As far as moveset goes:
Color bombs (Wario Woods)
Cargo Throw (NSMBW, SMB2, NSMBWU)
Ice Balls (NSMBW and NSMBWU) Easy recolor of Mario's Fireball with some different properties.
Pow Block -maybe final smash (...lots of games) There's a Pow Block on the Mario Bros stage. I don't know if that could be used or not.
Turnips (SMB2) Easy cloneable move from peach.
Toad's Go-cart (Any Mario Kart) He could use one of the karts from the Shy Guys on the Mario Circuit stage. Again, don't know if possible.
Spore Attack: Basically Peach's counter
Propeller Toad: (NSMBW, NSMBU)
Toad Tornado: (NSMBW, NSMBU) His version of the Mario Tornado
Super Squat Jump: (SMB2) This could be a special or just a unique thing where if Toad crouches for awhile, he's be able to jump higher.
Characteristics:
Toad is the fastest of the playable Mario characters
He's also seems to display big bouts of strength so he'd be slightly strong
He'd of course be the lightest Mario character
He'd has the shortest jump of all the playable Mario characters
He has short arms so he would most likely also have the shortest range
Plus, there's a good model on brawlvault.
