Cutter here's a musical thought I had in the past. It's completely from ROTS OST, though the mix is rough, some things are in different tones. It tries to be an alternative to anywhere you need to generate tension and release it with Darth Vader's theme. I guess if you like it, you could make it into something more subtle, or even re write it with your own home orchestra (?).
(The link shows up with an icon of an .EXE file, though it's just a regular wav. I already downloaded it and had no trouble)
Hope you like it, or at least that it provides you some sort of inspiration for a new SW related musical piece you had in mind.
