What I would suggest is putting in a small subpanel, like a 4/8, 70 amp. Keep in mind that u can't have more than 6 disconnects without a main breaker, which shouldn't be a problem since u will have 2 double pole breakers! U could pull 4 #6 THHNs in the 3/4" EMT and be ok(with code, maybe not your hands and back
