Actually, the whole TPM battle score is full of variations of DOTF, that includes the space battle, ground battle, and destruction of the federation control ship.

also there is choir in ROTJ when the strike team are subitting the security code for shield passage, also Endor already has a theme, the parade of the ewoks/forest battle.

And a bit off topic, apparently, the revised Sail Barge cue (not the alternate) may have been ghostwritten by Fred Steiner, who composed the scores to several episodes of Star Trek (and some cues from the first movie)!
