I’d suggest not bothering to keep it “chronological,” if it’s going to be a spinoff. Even moreso than numerical prequels, I would imagine it would be understood that the audience is already familiar with what came before.
And, just because I’d like to see it as part of a finished 3-in-1 edit, I’d advocate for Octorox’s opening framework: fade in with Lucasfilm logo, though perhaps no 20th Century Fox fanfare given your motif, and on the frame at which the opening STAR WARS logo would be, cut to the establishing shot of the ending TPM duel which originally followed Padme and company ascending via window. This duel would serve as a way to intercut bits and pieces of Anakin’s story so far. Works without a crawl.
He never finished his 3-in-1 edit, but I really like his opening.
Doesn’t every 3-in-1 edit start with that duel?
