In the early to mid 80's there were a few USMC helo types instructing in T-2 Buckeyes with VT-23/Kingsville. They never instructed in CQ, Guns, ONAV or OCF, but they were everywhere in the Fam, BI, RI, and Form stages.
Word on the street was that this question was asked recently and promptly shot down. One of the IPs in question was a former Cobra WTI/FAC(A)I/DACM(I)...so I'd imagine if he's getting told no, than it's a no for the foreseeable future.
...and who the F wants to goto Kingsville or Meridian anyways. Not to mention hang out with a bunch of condescending Navy jet dudes... (joking)
