Okay, using just this one shot for reference, seeing as it's handy -
The suspended 'Vent Pod' shown here is too narrow to incorporate the 'Carbon Chamber' for a start, and there are also 2 other shots that show the window that Luke fell through as being on the OTHER side of the structure, compared to what the 'interior' shots showed....which is wrong I believe. The other 2 are when we first 'zoom-in' on the suspended 'Vent Pod', and the other is when we then see a 'closer' shot of Luke making his way back along the narrow 'walkway' towards the entrance, after falling through the round window.
So the simplest thing to do of course, is to 'flip' the shots of the 'Vent Pod's' exterior into reverse, so that the window now seems to be on the side that Luke actually fell out of, according to the 'interior' shots. (Note: this particular shot above only shows the extending short 'gantry' that Vader duels with Luke on. The long 'extending support arm' should be seen added in, going off into the distance behind, somewhat level with where the round window is positioned, to match what is indicated in the 'interior' set
However, although Luke and Vader are small enough in the shots to 'get away' with 'flipping' them....it is still possible to see that Luke is wearing a gunbelt on his right-hand side, and this would be tricky to amend I'd imagine. On top of this, Adywan would have the issue of Luke also holding his Lightsaber in his right hand to contend with, as he first makes his way back along the narrow 'walkway' after hanging onto to it. He is seen to touch the side of the 'Vent Pod' a couple of times as he heads along to re-enter it. Both of these things would also 'reverse' if the shots were 'flipped', and will be tricky to sort. We'll see what he decides.
