What about MMOD protection?Aren't the ISS suits hard for a reason?From the astronauts perspective, how would the ACES handle a heavy back pack for extended periods compared to the current design?

Only the upper torso and helmet of the current EMU's are hard. The arms, gloves, legs and boots are 'soft'. MMOD protection comes more from multiple layers rather than from 'hardness'.And the term 'heavy' takes on little or no meaning in weightlessness. Mass, and more specifically, it's related inertia, is much more of interest.
They are not for EVA. They are for pressure loss on launch and reentry. (rescue suits).

If the MMOD protection is more from layers, then why the hard torso?
