You’d have to rotoscope I think, the other options are pretty impractical. It’s just something I haven’t really done before so I’m curious about how tricky it’d be.
It’s not that big a deal, no, but considering how little I feel these films need changing it’s actually very high on my list. As for IX, a time gap is a perfect explanation for fixing it. It’s just weird and doesn’t make sense why he gets the gold back at the end of TFA (plus I actually quite like the look of the red).
