Changing camber with camber bolts does not change SAI though.

Moving your SAI in that direction positively effects roll center, and doesn't really change your scrub radius much. Lengthening the control arms changes your SAI the same way. There is nothing wrong with either.
Messing with the knuckle effects the wheel's relationship to the steering axis, which is a whole different ball of wax. Will it work? Yes. Should you test both ways? In my opinion, yes. There are a lot of different ways to optimize the McPherson front suspension depending on your goals, and there isn't really a "right" or "wrong" way to adjust camber, as long as you don't take things to extremes.
