Default Secondary butterfly question/theory...

I've been doing some researching on secondary butterflies and i've come to find out that what causes them to open is the engine creating enough vacuum and WOT which pushes on a diaphram which opens the secondaries.
Now, here is my question/theory.


If you are running boost and (for arguments sake) a GE vacuum manifold, would it be possible to run one nipple from the VM to the diaphram? Then, if you are running say 15psi, put a boost solenoid (i think that's what you'd use) inline between the vacuum manifold and the IAB diaphram that would open it at a specified psi? In turn, wouldn't that give you more air above that set psi?
Thanks in advance for any help clarifying this.
