I have BKB236 hangers that also have super short axles (32mm non-threaded length). Evolve’s plastic pulleys had too tall of a stack height to work. Boardnamics metal pulleys did work, however. BKB236 hanger is thicker towards the middle that I had the Dremel out. BKB Caliber II clone looks like it has a uniform clampable cross section, so you may be OK there.
