I assume Blake will build a new set of LCAs using his design but retaining the RSRT pick-up points/geometry. Moving the pick-up points changes all of the current suspension geometry. Changing the effective length of the LCA would, for example, require a different length or repositioned rack to retain proper bump steer. The angled (not parallel with the centerline axis) pick-up points of the LCA move the lower ball joint fore and aft slightly with suspension travel, which affects dynamic caster gain, which I'm sure is a deliberate design feature of the current configuration. Moving either of the LCA pick-up points up or down changes the roll center, dynamic caster gain, and/or anti-dive. And as you point out, changing the relationship of the UCA and LCA lengths changes the camber curve. Lots to consider.
