No idea of there is a specific pipeline for it.
Are you looking to revert to warrant or stay an RLO? Medical branch would allow you to go fly helos (60s/LUH) without going warrant. Otherwise your a general aviation branch officer, and most likely win them now going fixed and helo pure in the progression pipeline you would end up in a c-12 RLO or Warrant. They just as of last year went to that model though so there is a lot of speculation on it.
