Shaak ti already is 'out of there' - just don't add her deleted scenes ;) - As for the rest, some of the deleted scenes from ROTS were never polished up to final movie standard like the other films. Several shots include poor resolution, poor compositing or "property of ILM" watermarks.

I think the 'rebellion scenes' are okay tho, which would really be all that ties to TFU. Not sure exactly where they are supposed to fit.

It might be possible to trim Shaak ti from the early scene where the Jedi encounter GG but since the following part is imcomplete i doubt there'd be a lot of point. you'd probably also have to tweak some exisitng scenes and dialogue to accomodate such an alteration.
