Yeah, team Jedha all the way!
The thing is, we can’t change the fact it’s another desert planet, and I feel like drastic changes require too much vfx work or wouldn’t be really believable anyway. So, we could at least add more flavor to an existing desert planet rather than it being a brand new one that almost looks just like another desert planet.
Also, it makes sense that a Jedi hunter like Ochi would go to a world like Jedha. Why would he go to Pasaana, of all places? It seems like nothing is there. Even the Aki-Aki feel more like visiting pilgrims than natives (which fits well with Jedha, since it was also called the Pilgrim Moon).
It was also known as the Cold Moon, although I don’t know how the Death Star test would’ve affected its overall climate. It could’ve triggered a nuclear winter. So, perhaps if you could add slight hints of snowfall if you really wanted to make it stand out from other desert planets. But the first thing I would try and do would be to regrade the Pasaana sequence to match Jedha in Rogue One as much as possible.
It also makes sense for their to be random First Order patrols on a world like Jedha. I mean, was Pasaana really significant enough for their to be any there?
This might be taking things too far, but since Jedha was mine by the Empire in the past for its kyber crystals, what if after the serpent Rey heals slithers away, while Rey is looking down, she sees a small yellow kyber crystal sticking out of the sand? Not sure how exactly you could create the shot, but it might be a nice way to set up her yellow lightsaber at the end of the movie.
