The best tracks Williams did for Star Wars were copied almost beat for beat from Mussorgsky and other composers. George Lucas discussed in a few interviews over the years how he would write scenes to music then get John Williams to compose a track that evoked the same emotions. e.g. Duel of the Fates is just a remix of O Fortuna by Carl Orff.
If Abrams uses the same technique to score his film any composer will do.
