do you have an aero rating already?
Used to be units in conversion could get waivers for their nav/wso's up to 34 if their aircraft conversion was displacing those guys from jobs (F-4s to F-16s, KC-135 Avionics Upgrades, C-130E/H to J).
If you are already an NFO, maybe they can convert your Aerorating to AF equivalent Nav/CSO wings, then send you to UPT that way. I have seen quite a few Army rotary wing guys come through lately for ANG units and they are already wearing AF pilot wings at UPT due to the converting of their aero rating. Unfortunately, the only game in town on this conversion thing right now are the guys going to UAVs.
Until they figure out how to train a UAV track ab inito, the ANG units are sending guys to full on UPT to give them options with other ANG units down the road should they move or units close/change missions again.
