Maybe he should just stick to a solid moveset.
He has some games to choose from.. Pilot Wings 64, the Bowling game... and who knows.. maybe get some moves from the Comic. (Though it'd be hillarious for his Final Smash to focus on him and HOWARD)
Nester had a cameo appearance in STARTROPICS.
When a fisherman asks you if you know the ABCs of fishing. If you answer yes, he then asks:
"Is your name Nester?" (I didn't get it back then, it was afterwards that I got to know who Nester was)
Nester Alternate Moveset:
B: Random B attack (Fire Ball, Bow, Shield Braker, Falcon Punch... etc)
B Over: Throw bowling ball (charge for speed and strength)
B Down: Cannon fire (set up a cannon, and fire yourself).
B Up: Jet pack (would work like Diddy Kong's except it wouldn't blow up)
Final Smash: Call on his chopper, and fly around hitting everyone with propellers.
I say Nester is possible.

Just not probable... But he's definitely a face I want to see in Brawl represented somehow... *snif* miss those early 90's...
