BEags, but would it save that much money?
You would be paying them all as Fg Offs and surely getting them all through the system in a reasonable period of time - say 6 months - instead of stretched over three years would mean massive restructuring (and holding for the studes!)
You would also still need to retain the entire infrastructure to accommodate the guys just having air experience. Seems to me you're advocating a return to the days of the UAS flying club and a Cranwell flying academy! Progress?
Not having a pop at all just can't see it working very well. And, how would the civvie contractors and MFTS fit into all this...?!!
