Three Wheelin'
Couple of suggestions:
Mazda RX7 FC rear subframe. The whole car is copied off the 944, you would be surprised how many parts are "almost" interchangeable. Pretty obvious that Mazda started with a 944 as a development mule. So this should fit surprisingly well.
Love the geometry of the FC rear end, hate the toe-steer arrangement which adds weight and doesn't work on the track. I actually bought a complete subassembly back in 1995 for evaluation...
The geometry is fascinating, it gives twin arm geometry but in the 'vertically challenged" space of a semitrailing arm.

We have a Mazda FC Lemons car, when I was doing the alignment I was a bit put off by the goofy rear camber adjustment. Our car has an adjustable vertical link at the rear; changing its length moves the entire rear part of the subframe up and down, thus changing the rear camber of both wheels at the same time. More modified pieces are necessary to adjust rear camber individually.
I think I'd do a Kokeln-style rear end and be done with it. Maybe incorporate something similar to the 935 style rear camber boxes for fine tuning:

Would have thought there'd be quite a few similar looking trailing arms on other cars over the years?
