Rear ride height affecting camber? Dumbass I meant Caster D’oh!!

I wont be doing this anytime soon, as according to my wife I have other much more important non Mopar things to take care of right now.
Again from looking at other threads on this subject, although offset bushings from Moog offer the ability to add some caster, that is limited and might still be reduced somewhat in then adjusting for negative camber and I guess also from an engineering POV they are a bit of a compromise. It looks like the fixed UCAs from QA1 which have a built in additional 3degrees of caster by shifting the ball joint location back would be the KISS way to go as this additional caster is not reduced by adjusting for camber (total caster from the QA1 arms and adjustments to the control arm mounts obviously would change) and it doesnt involve compromising the structure of the bushings or extreme settings on the control arm mounts. Would that be about right?
