When I started this, the Special Edition versions all had the prequel-era logos. So, for a Custom SE version I figured that’d feel right.
However, at least ROTJ would use the new 19SE as a source, which uses the modern LFL logo (which does not feel like it fits with the opening fanfare).
Rather than feel like the OT should try to “pick a side,” I would just rather let each trilogy have its own distinct opening flavor. No fuss and avoids awkwardness.
