Form drag is HUGE.
The problem you would solve with this would probably not be measurable.

It's not about skin friction.
By sucking out the stationary boundary layer you get less flow separation thus less drag.
In practical terms you get lower drag equivalent to a more aerodynamic shape.

Beyond certain speed the power required to power the pump is overcompensated by the lower aero drag.
