If you're going to put the Jabba scene back into ANH, it only makes sense, IMO, to remove/drastically edit the Greedo scene. You can't keep the both of them as they are together without unneeded redundancy creeping in.

And it would've sucked even more. Imagine the viewer reaction to "omg, they inserted a scene with some redundant exposition!", and now compare it to "SHIT JUST GOT REAL, LUCAS RAPED THE GREEDO SCENE SO HE COULD HAVE CG JABBA IN IT AHHH!!!!1!!".

It sounds like a nice idea, but only as some sort of DVD option (or special feature) that would let you watch it (seamlessly) as an alternative version.
Then they could've tweaked the Greedo scene somewhat (the "even I get boarded" line probably even fits better with Jabba), tweaked the Jabba one, too, and then have it all fit together.

But just cut out chunks out of Greedo and then put it on the DVD like that? No Wai!
Removing it? Doesn't work, they keep talking about Greedo in the next scene.
