Some ideas i have thought up:
Im gonna add a pretitle squence of events during the old republic (KOTOR times) form some fan movies. Episode 2 is gonna include Han Solo and millenium falcon (thanks to blade runner) and the timing of the saga is gonnacondense (years i mean) so luke is born in early ep2.
loads of usual twekas ghosted qui gon etc. these are some quick rough ideas.
