And if this makes any sense to anyone other than me, this is how I would do the 3rd wheel assembly.

Green is a car spindle (rwd car no driveshaft through it)
Blue are ball joints(upper and lower)
red are heim joints
black is frame tube

upper ball joint would be fixed against a load bearing hoop
lower ball joint would be on a single A arm, adjustable for caster
the front heim would be adjustable for toe

The 3rd wheel would be based off of a mcphearson strut assembly, without the actual moving suspension (3rd wheel suspension has a habit of flipping the car mid corner). The structural hoop would replace the strut and be fixed. This design gives maximum adjustability while requiring the least amount of space from the passenger platform

It looks like a good design. You have the adjustability you need while still keeping it simple. The thing I would be especially cautious of is where the sidecar structure was mounted to the rest of the motorcycle. Make sure all attachment points are solid with no flex (I'm primarily thinking the subframe). It would be a bit of a pain to hit a bump and have the geometry of the sidecar wheel change.
