A Star Wars detective film is a nice idea but depending on the execution it could end up being better or worse than what we got. I don’t see it as being inherently better but if you do that’s fine; we’ll just have to agree to disagree as usual. I think the best way they could have done with a story revolving around finding Luke is to have both The Resistance and The First Order have a piece of the map but have a 3rd party have the last piece and the film would be a race to see who gets to this 3rd part first. Instead of clues to where Luke is we would be getting clues to where this 3rd party is while getting information about Luke in general.

That plot device was common during the cartoons from the 80’s. Both the Good & Bad guys had a piece of map/weapon/item; meanwhile a third party had the final part of the mcguffin, and there’d be fight for it.
G.I. Joe did that a lot, heck, they even had a weapon called “The Mcguffin Device”.
If I saw that in Star Wars, it may make me think of those cartoons.
