maybe the more space battle we have the less ewok we would need. do you think that with the DSIII twist, the Imperial ambush on ednor wouldnt be necessary? so han actually blows the place up first time?

I think you still need it but with better Ewoks and less slapstick.

The ground battle/space battle/sabre duel trio needs to remain but it has to be improved so every element shines.

The action highlight of ANH was the space battle, the action highlights of ESB were a ground battle and a sabre duel this film ends with all three in a way we haven't seen before and that's necessary not only as the end of this trilogy but (unless George changes his mind) the end of the whole saga.

Ewoks which act like real believable primitive but brave creatures are fine, silly teddy bears with pebble eyes hitting themselves in the face are prototype Jar-Jars.
