I’d personally rather see deleted scenes as extras rather than as part of a supercut. If there’s one thing the SE proved, it’s that deleted scenes get deleted for a reason.
Making a purely extended edition doesn’t make much sense to me, since it would certainly kill the pacing. On the other hand the extra footage can be used to create an alternate cut, omitting some stuff from the official release while adding other material.
Also as far as the SE goes, the Jabba scene is an unnecessary addition to say the least, but I think the brief scene of Luke and Biggs reuniting on Yavin is a must. If only we could recover that scene in it’s entirety…
