All that really needs to be done to fix the Endor ground battle, is to insert some home made trooper vs rebel action. The Ewoks fighting for the their home is not necessarily unbelievable, it just shouldn't be center stage. If a bunch of short battle scenes were intercut into the current footage, showing more rebel grounds troops in some action, then it would fix everything, IMO.
honestly this is probably the best suggestion I've heard...
