I think battu works as a location that you can just clump all your star wars stuff into. tying together geographically disparate parts of the setting. Can't have rain or porgs on tatooine nor can you justify a Bantha or a lightsaber seller on endor. The problem is that Things in star wars are just as chronologically isolated from each other as they are geographically.
The only things taking place in sequel era at the moment are the x-wing film and galaxy's edge. Can't tie into the mandalorian, can't have darth vader, can't have obiwan, can't have yoda, can't have clones, can't have ashoka tano, can't have luke skywaler, can't tie into the bad batch, can't tie into the high republic. 70% of the popular things in star wars are separated from galaxy's edge by a matter of decades.
Now if it were up to me i'd have galaxy's edge rotate through seasons. A third of the year is set during the clone wars, a third of the year is set during the galactic civil war and a third of the year is set during the race for galactic supremacy. Hondo ohnaka was alive for all three periods so smugglers run wouldn't have to change that much.
retheming rise of the resistance is harder but i think it could be done if you just built the ride to be different from the ground up.
