The pistons rise because atmospheric pressure on the bottom of the
piston is greater than manifold pressure applied to the top side. When
you pressurize the manifold, I'm not sure the pistons won't stay firmly
seated!
Presumably, if you encase the ENTIRE carb in the pressure plenum,
it'll work - that is, create an artificial 'atmosphere'. All outside air has
to be accounted for and blocked. Oh yeah - this involves the fuel bowls,
too! You've got to compensate (raise) the pump pressure to adjust for
the added boost as well!
Now you see why EFI is used with blowers...
