This is a good idea.
But I’d use Jabba’s dialog from the SE scene and add the shot of Jango in Jabba’s palace.
I’d also cut to Jabba after Han shoots Greedo. Jabba knows about his somehow, and sends Jango to pressure Solo one last time. Latter on we show Jango + thugs by the falcon (ending of the SE scene). Perhaps keeping of Solo’s dialog in the distance as Luke arrives.
So it’s the same story as the SE, but with no CGI 😁. Also a nice introduction to Jango.
