I personally don't think this would be a good idea, I don't like the principle of reusing cues from other SW films to put them into another one (this is why I have the Purist version of ANH): look at AOTC and ROTS, it just sucks how they copy-pasted the music from TPM ><
And what would be the point exactly? I mean think the music just works fine as it is IMO, and where could the Force Theme be put during the battle?
I didn't mean to sound rude at all (sorry if I did, my English sucks at times :P), it's just that I didn't like the principle of added music in ANH:R (even if Ady had his reasons, which I don't discuss) :)
PS: "Goodbye Old Friend" IS epic yes, but the fact is where could this be put into one the OT movies?
