It's a classic source/sink problem in fluid mechanics. You can't suck out a candle.

Most everything in single phase, low Reynolds number flows is about the interplay of inertia and viscosity. Viscosity acts to run out all motion while inertia is essentially your kinetic energy. If you're going to suck flow back through a nozzle it's not going to have much directionality.

Maybe you could exploit the Coanda effect.
