any chance the D+/- lines are broken out to a couple pins?
I was never officially diagnosed, but I was having so much pain a couple years ago that after a day of work, I'd just go to bed. I picked up a sweep from keebmaker and within just a few days I noticed it was the right way to go. The only time I notice any pain now is after a day of heavy cellphone or mouse use.
broom (of ferris sweep) did a promicro "tribute". Dunno if they ever actually released it, but it's up on github: https://github.com/davidphilipbarr/testing-boards/tree/main/gogo-corne
One unfortunate thing about ergonomics is that each persons needs are different. No one can tell you what's best for you, but luckily we have a lot of good options that help you find what does work for you.
If you're fine with some soldering, there are a lot of open source splits that you could get fabricated for pretty cheap and end up with two full builds. Cantor, Piantor, Corne, Lily, Sofle, etc etc etc. The low cost of having them fabricated and built yourself can mean trying out a few different keyboards to see what works best for you.
When it comes to gaming, maybe using one keyboard for programming and a different keyboard for gaming. It could be just half of a 4 row split, a gaming focus keypad (like the Eternal) or just your current rowstagger board. I personally use a QAZ-alike I designed as a gamepad.
Tenting can be accomplished multiple ways. Some boards have Tenting Puck support. Some can have large bolts added to adjust the angle. For boards without some native tenting support, many 3d printable cases exist that provide tenting and lately I've seen a lot people use the magsafe sticker thingies to attach their keyboards to small tripods.
One reason there are so many options is because it's pretty easy (and fun} to design your own keyboard. It's not uncommon to try a few different designs/layouts to see what works best for you from each and then design a keyboard to fit your requirements. Designing your own keyboard comes with it's own set of information overload, but there are a lot of us around to help us.
If you're down with DIY and Stateside, hit me up. I've got a bunch of PCBs in a box that I can part with for stupid cheap. I'll need to take an inventory of what I have but if you're interested I'll gather up the info. I know I've got at least an MX Corne.

Yeah, lol. Red is one of my least favorite colors.
Nope, they were too red for me. If the crystal reds were 5pin I'd use them a lot more.
Sadly, I don't think there are any choc boards that fit your requirements. Not many choc boards over 40% and the ones that exist will require soldering of some sort.
Unfortunately, there aren't many options in the 60%+ range.
Cepstrum (sp?) From keebio is the most recent one I know of, but it's a split. There's the Chocolate Bar, mt-choc and Pete (of ZMK fame) is working on WarDriver - a choc minivan - but it hasn't been released yet.

Put me down as a pinecil lover. These things are great. I had a TS100 before, and while it was very nice, the pinecil is superior
Silvers are my choc of choice right now, but I like purpz/pinks on the pinkies. Pro Reds are a good option too, being just a lil lighter than silvers.
I don't know how valuable a scheduled post directing people here would be though, so probably not worth putting a lot of effort into.
just thinking about those designs where a case is wanted, but the position of the usb port isn't ideal. not one of those things that I think is required to make this a great controller option, just something a lot of controllers don't have and I've wanted for a bit.
