Here's my solution to easily adjustable rear wishbones without having to remove them to adjust.
We solved this by using "barrel" nuts, essentially the bush or rose joint is screwed into the centre of the barrel nut and the outer thread of barrel nut screwed into the wishbone. To adjust you simply release the lock nuts (one on barrel nut to wishbone other on rose joint to barrel nut and adjust barrel nut.
Here is photo as fitted to my 26R:
Note, this photo does not have the barrel nut lock nut fitted which we did to be sure and to provide additional support for the barrel nut. Also when finished the thread was shortened to ensure it was inside the wishbone, greased and caps fitted to stop grit getting in.
I've done same on a road car with bushes which using an adjustable inner bush (like Spyders). In this case we've only use a lock nut on the bush to barrel nut. as the bush does rotate. The road car has steel barrel nuts as the maintenance.
Hope this simple solution is of use.

I know I must be missing something here, but can you please expand?

The barrel nut isn't threaded within the wishbone, only at the end that accepts the nut.....

Thats exactly what I thought unless the rose joint had a L/H thread?

The wishbone has them on both inner ends, so to adjust either wind barrel nut in or out, one to adjust toe and both barrel nuts to adjust camber.
