AF1's 100% have the same height hangers on hi's and lo's. The only difference is the baseplates, therefore yes, a hollow AF1 hanger of any size can be used on a hi or lo baseplate.
The lo's have better kingpin clearance than the hi's, and they shrink the wheelbase. So to kinda make my AF1's turn into classics, I'm running stacked Ace risers (1/16" Ace shock pads under the 1/8" Ace shims) which brings them to 54mm height. Paired with 52mm wheels, pretty much zero wheelbite and insane turning. I did this mainly because I liked how the classics turned better, and the AF1's offer better strength so I get the best of both worlds now.
