I guess if I had my druthers, I’d do one of the following:

Recast the lead characters and film Zahn’s trilogy as the ST. (Sebastian Stan as Luke, Millie Bobbie Brown as Leia, and give Alden Ehrenreich another shot as Han.
Go with Prizm’s ST story. (Available to watch on youtube)
Redo ROTJ with Luke falling to the dark side, and then a ST in which a New Republic led by Leia is at odds with an Imperial Remnant ruled by Luke.

Oddly enough, given the timescales involved, 1 and 2 could be combined if you resolved the issue of Leia being pregnant with Jedi twins in Zahn’s trilogy vs. Ben Solo being an only child in Prizm’s story. You could rework Jacen / Jaina into Ben / Rey, with Rey having been lost to the dark side early in her training. (In Prizm’s story she just starts as a fully trained darksider.) Then you’d have Zahn’s trilogy as 7-9 and Prizm’s as 10-12.
