Here's what I remember Adywan saying about these things, artego:
He's not doing the things in the list because he doesn't think Empire needs any of those things, as (in his opinion) it's almost perfect as-is (or, as was, as the case may be).
That's the same reason why he will not be adding in any new scenes, regardless of what shows up on the Blu-Ray release.
However, he has not ruled out using deleted scenes from Jedi when he gets around to it, as he's going to be making radical alterations to that film anyway. It really depends on what scenes are released, too.
