I don’t think the creators of SC38 ever intended it to be edited into ANH; it’s meant to be its own standalone piece of media.
I’m very much a Theatrical Edition purist when it comes to ANH, but if I was going reshoot the Ben vs Darth duel, I’d do a short, terse, Kurosawa style kendo/samurai fight - like Rebels eventually did with Kenobi vs Maul.
