Is it possible for a hack of Pokemon Trainer that sends out Snake, Marth, and Olimar instead of his Pokemon?

Nope.

Why not if people do character slot swaps all the time? In theory, the switch move could even be on a taunt, since taunts and moves seem to work similarly. It's less that I'm trying to argue and more like I'm less experienced and it doesn't make sense to me when people replace characters with other character or brand new characters all the time.

Well, if you want to get extra technical, it's possible to put the models on those characters. BUT:

Sorry but you are not allowed to view spoiler contents.

TL;DR

You'd have to be an expert in every field from 3D Modeling to Porting to PSA to even attempt it, and it'd STILL be near impossible.

HOWEVER, if you just wanted to put different models on the Pokes and make a moveset, you could still do that. They'd just have to have around the same filesize as the original.

Thank you, that was very informative.
