I've just mentioned this elsewhere but it deserves a mention here.

Do we actually need to see Yoda in the PT at all?

Remember in the OUT how we heard about Jabba but never saw him until ROTJ.

What if throughout the PT there are mentions of this powerful Jedi Master but the name is never attached to anyone we actually see.

He could be any of the others or he could be someone else so when Luke finally meets the great Yoda it really hammers home the physical incongruity.

Most of what Yoda does in the PT is out of character with what he does in the OT and the rest of it doesn't really add up to much.

I really like that idea.

Or, if you had to, you could leave him in as a background character for one scene, but leave him un-named. That way, if someone was watching the movies according to this mythical, hypothetical, crazy-butt scenario where somehow they didn't know a thing about Star Wars and were tested like some lab rat and made to only watch fan-edit versions, they then could see Yoda in ESB and say, "Hey, there's something familiar about that puppet guy. I don't know, maybe I'm crazy."
