Didn't the AF open up 50 or so slots for Green to Blue, provided they went into certain AFSC's? I'd be surprised if those weren't already filled, but it doesn't hurt to look into them. Someone has to oversee that program, they won't have it in the hands of recruiters. If you could find that person's office, a phone call wouldn't hurt.
You need to understand: the AF is cutting Airmen, it is very reluctant to bring in an "outsider." Combine with the AF and Army's animosity towards one another and you have a long row to hoe. The AF would leave those slots unfilled (and has) before it would willingly take a branch transfer.
