I loved the tv spot that used Duel of the Fates so I took a stab at recutting the song to fit the first section of Rey and Kylo’s Duel. Did some color correction as well.

I was against this but I actually think this works pretty well. I’d be worried about it seeming like it comes out of nowhere in context, but maybe you could tease it in the preceding scene (and maybe even the Force duel as well).
One thing I’d do personally to differentiate it is use the instrumental only version, especially as choral pieces are less common in the ST scores.
