Besides getting a 52-52mm coupler then a 39-52mm step up ring, is there any other method for mounting the 52mm threaded lens onto a 39mm thread lens?

Before you might say that I should use a different lens/lenses- I did seriously consider that, but I've also read that the diameter and/or aperture (or maybe it was the exit pupil size) of the wider angle lens should be greater. If this is certainly true, then if I can get this to work with a single adapter, there's no better way that I'm currently aware of, except my own unless perhaps I might be able to be successful with a manual vintage lens. at this point, I'd need to spend about several hundred dollars for a more modern setup. If got the 7artisans 60mm F/2.8 along with the Viltrox 23mm F/1.4 to couple with. I know, there are almost certainly better options of lenses that I could've used, but it's what I've got and hopefully I might not need to use a different lenses for the macro coupling. The distance between the lens elements should be as small as possible- which is the main reason why I don't want to use a step-up ring.

That's the most practical way to reverse mount a lens face to face.

The front lens acts as a diopter and a couple mm shouldn't show up. You might need the space to clear the outer surface of the lenses.

If I machined one, I'd do a mock-up with step-rings anyway.

FWIW, a lot of old slr primes had 52mm threads.
