Very little of a plane's lift comes from this, almost all of it comes from the angle of attack. Stick your hand out the window of your car, directly into the wind. Curve it, notice any difference? Now angle it up.

The only way I can think of to leagally create suction (good suction) is to use pnumatics to move a plunger inside a tube. If done right you shouldn't lose any pressure.
