Would this 'Super M1' helmet be usable with Level IIIA soft armor + ESAPI plates like modern infantry, or would it cause more fatigue?
It isn't impossible but it would be undesirable. The flared rim is an artifact of how it was made (repeatedly hammering a steel plate) and simply won't be present on a composite helmet unless its added intentionally and there is no reason to add it. The M1 also didn't have any accommodation for earphones & the chinstrap was on par with what was common in its day but is quite inferior to modern helmets chin straps.
So it wouldn't look like the M1 helmet really.
