Flight school max age is 32.
Speak with your state's warrant officer recruiter, and I think you'll find that you'll need another few years to make WO -- particularly now that you've had a break in service.
My recommendation is for you to get back in service, complete BNCOC, and then apply for WO. If you don't get selected, you can always reapply the next year.
