Maybe, just forget it and weld the spring hangers and just cut them off
and replace them if I need to change the function.

Why not fabricate two or three sets of hangers and weld one set on
now. Mount the springs with anti-sieze on the bolts and cottered
castle nuts. To move them, flip the trailer over, weld on another set
and move the springs. I think squaring and aligning the axle assembly
to the tongue would be hard to do with the complete, installed axle
but simple for four hanger lugs strung onto a long threaded rod..
