Massive caster variance Side to side

when I got my car aligned, even w/the moog problem solver UCA bushings installed for max caster, they were only able to get about 3.5 degrees.
Is that the offset moog bushings? Or just the standard ones? +3.5 would be awesome for me. After looking at this whole setup for so long, it looks there is room to bring the lca forward im shocked nobody has invented a swivel pin that draws the lower arm 1/4” frontward for increased caster.
