In case anyone reading this thread would care, I am in the process of rendering out ProRes master video files from FCP7 for my fan edit projects. Combined with the lossless audio outputs this will make things future-proof and available to anyone.
My edits of Ep1, 2, 3, Rogue One, and TFA are available now via the Google Drive, with the others to follow. (For the OT I might just export clips because one could just drag those clips in to replace equivalent portions of the OTD source.)
