To achieve the reverse, ie water pressure is higher than air pressure may be more difficult. May require redesigning the nozzle. Perhaps contact the air nozzle maker, they may be able to help.

From what I understand, there's a big difference between an internal mixing atomizing nozzle and external mixing. It seems as though the internal mixing requires higher air pressures while the external mixing requires less.
I was thinking of experimenting with this with a cheap HVLP gun I have at home as those are externally mixed.
I'm wondering if one could drill out the center orifice for a standard aquamist nozzle whilst pressurizing the external air ports for increase atomization. Maybe I'll play it with this weekend.
