This is my version of your option 3. I am deeply indebted to this forum’s grandees for the necessary pointers that helped me put it together and it’s not really original because of the work they’d already done. With
@kingkorg and
@Wordsushi deserving special mentions, as well as Jules Rykebusch for the circuits.
So it’s dual OPA Alice, CMOS inverter at 80v on a 797 CY002 in an “Ali ‘47” housing. I have also used kingkorg’s / Wordsushi’s foam mod at the base of the capsule, around the pedestal too because there is perhaps a touch of resonance in this headbasket.
I own the OG Townsend L22 since a few years but I now no longer have to bring it between my studio and my home because I’ve got another option! It sounds almost identical.
Costs: Capsule at £40, body about £60. Circuits built for about £40 (can be done for less I expect). Misc connectors, wiring and adaptation for fitment brings it to about £150 plus my own labour.

This is closest to the L22 / DLX in my view. From what has been discovered by kingkorg, the LX no longer has a hardware de-emphasis built in because the UAD version of the latest plugins does that work in software. Therefore, you need to run the EQ curve before the old plugin to get the best emulation accuracy, I think. If you already have access to the UAD plugins, you can just select the LX as the input mic and you're off to the races. The view seems to be that a slightly smaller "LX" sized body would make a better match for this, though.
Inspired by those with incredible knowledge on this forum, I am spurred on to try more ambitious projects. A K-47 based mic next I think. Probably all old hat to the trailblazers but exciting territory for me and hopefully a distinct flavour of microphone compared to what I have already.
