My WEG collection has been used as reference material for EVERY Star Wars game I've run regardless of system used.
Most of the WEG adventures will work well for AOR as they tended to assume the PCs were rebels.
If you read the forums a lot of things refered to as canon came from the WEG books and not the movies. The original EU authors were given WEG sourcebooks as reference materials when writing their books according to interviews they gave.
And the rest assume vaguely rebel-friendly or neutral merchants. And thus work with Edges just as well. For example, Otherspace.
WEG was brilliant in its time. It's starting to look rather shabby now, and some of the concepts are antiquated at best.
A few concepts got returned from the grave in Edge of the Empire - like abstracted range bands, which went away in WEG 2E. They're great for certain cases, but a problem for a wider range of cases. I didn't like being hemmed in by them in WEG 1E; didn't mind them in Edge, but with the different focus and scope in Age, they again feel like a strong hem.
