Sadly not

Ok.

using a belt sander isn't the end of the world

Good to know!

As for the bits around the doorframes, I really think you'd get away with using some slim trim or scotia.

I can't get my head around how this will work, given the variation in gaps, variation in shape of door frames, and that some of the gaps go under the doors themselves.

You can always fill the gap with something as well. If you do a sample of the same wood and do a couple coats of Polyx, you'll be able to pick up a Bona filler that will colour match pretty well

Probably the most feasible option.

Every time I think about doing this I frankly come close to crying, and in fact have done so, it's just such a shit situation because I'd be happy to pay someone to do it, but following that route has just wasted weeks without getting any progress. Last time I felt like I was up against it for time was actually the start of this whole debacle, so I'm wary of doing the same thing again.
