The big problem with this arises from trying to adapt it to the existing engine electronics. There is no more reliable vacuum source from which to do speed-density tuning (MAP and IAT). MAF engines should not have this problem, though.
A secondary problem arises from implementing engine idle. That's pretty much independent of whether the engine uses MAF or speed-density.
A tertiary problem arises from powering vacuum-dependent accessories, like power brakes and cruise control.

Have all of the intakes pre throttles go to a single chamber the inlet to that chamber can have the MAF sensor.
They make an electric brake booster, it shouldn't be too hard to rig in as it is typically smaller than the vacuume based booster.
