So it looks like there will be a film set prior to ANH, with the continuing potential for more standalones in the future.

So here is a radical and obvious idea for some PT edits - use these alternative films to displace/replace the current PT.

They won't follow the skywalker saga necessarily, but does that actually have ot be the focus of the saga? What if a heavily editted AOTC became Ep1 for instance, or maybe we even start with ROTS? Something to hope for anyway.
