Quentin Tarantino's "preferred" 10th and final film?

[KManX89]

As we all know, QT has "made" 9 movies and said he "plans" to stop at 10. Whether you believe it or not is a matter of personal opinion, but we do know that, at one point or another, QT was attached to write and/or direct a 3rd Kill Bill and a standalone Star Trek movie, both of which have seemingly fell through.

Which film would you have "preferred" for his supposed 10th and final film? I know the obvious answer is "I'd prefer he do something original", and I'm with you on that, but given the choice between established franchises (one of which he created) for his "final" outing?

Personally, I would've preferred Kill Bill Vol. 3. There's still a bit of untold story left with Green's family tracking down and killing The Bride, which was the rumored plot for the film involving the now-adult daughter. Plus an R-rated Star Trek just feels totally unnecessary and doesn't fit the franchise at all (see: Star Trek Discovery and all the "not feeling like real Trek" complaints from fans towards its gratuitous gore, F-bombs and even Klingon rape (!) in one episode), and I've more than made my thoughts about "dumbing down" stuff known.
