Jedha’s the best option because it’s practical and interesting. And in terms of cobbling together the word “Jedha” to replace people saying “Pasaana”, pretty much everyone says “Jed-i” at some point, then you just need a generic “uh” sound, which should be easy to find.
Pasaana is named twice in the film. One when Rey says she’s gonna start her quest there, and one when a female Imperial officer reports to Kylo about the location of the necklace.
Rey’s delivery is rather mild so redubbing it would not be difficult to redub to Jedha, plus there’s plenty of places where she says “Jedi”. The other character is shown from the sides so her mouth movements are less noticeable and I’d say even easier to lipsync.
Jedha is not that unique in the visual aspect (even though someone could make the asteroid field visible from the surface, to make the sky look more alien) but I’d rather have a familiar planet than a new one that doesn’t look new. This could make for a nice editing collaboration.
Changing the color of Ajan Kloss is also an interesting idea, though likely more time-consuming as that planet features heavily throughout the film.
