I like the idea of a screw jack versus a hydraulic jack because it won’t sink over time while you’re repairing the tire.
I made some progress on the PA46 jack:
It is a combination of those items:

https://bogertaviation.com/products/pa-46-main-gear-pin
So far it seems to work well. It is 3,4kg including the wrench. It can pick up the axle very low if the tire is flat and it raises the plane quite a lot if required.
Can you not turn the adapter 180 degrees in the axle to raise the jacking point? it would also provide for a more stable jacking configuration.
The adapters are keyed due to the retaining bolts inside the axle, so currently only fit one way. They were actually custom designed to match the Tribal Jack and are deliberately low to avoid having to jack up too far. If l were using a different jack then they could easily be redone to accommodate a higher clearance.

If you can’t fit a bottle jack under. a toe jack should work. Either with an extra lug welded on at your required height or just spaced up as needed.
I am currently doing the annual on the Jetprop so was able to dig out my jacking adapters from my travelling spares stash.
I have never thankfully had to use the nose wheel adapter, but have had occasion to use the main gear one a couple of times. Works like a charm.
These were fabricated by a local engineering shop.
I still need to use the tribal Jack with the low lift plate to lift the wheel since the clearance to the floor is very short and unless you can find a miniature bottle Jack l think you struggle to get a normal one to fit under that space.

That seems to be it. Needs a standard bottle jack to operate:

I was actually told Bogert makes an adapter which goes into the axle nowadays. It is not on their website but I will write them an email. My 2 year old version seems very solid. Moving the brake line is no big deal when fixing a tire issue. But on mmopa people suggested to use the lift for getting more fuel into the tanks and for that purpose an axle adapter is obviously far superior.
Very interesting, why did you not use the adapter supplied with the Bogert jack which goes unter the axle? On the main gear you have to push the brake line to the side but besides that it seems to work?
I didn’t want to mess with the brakes when stranded somewhere under a time constraint, and I also worried about the stability of the supplied plate, which was a very early version of the jack. They may have improved things on later versions but with mine the support seemed to angle down under load and I was concerned the whole thing might slip off.
