that scene is great just it is. you can also be too zealous some time...
i think that, if this is really true, the only thing that could stop them would be the special effects not being good enough to make it look credible. although, that didn't stop them from putting that jabba scene in ANH.
but on the plus side, as samatar said, there will be more people yearning for the OT in this case.
and maybe they planned to do that at first but dropped the idea. perhaps that's why they wanted to wait till ep3 was released to release the DVDs. they saw that it wouldn't work out so they decided to release the DVDs earlier. i think i'll go with this explanation. living in denial is so nice...
