According to his toy review, Siege Jetfire comes with a cockpit that can seat a Titanmaster or Primemaster figure.

Because he shares a color scheme with Minerva Titanmaster, I thought it would be fun to acquire her to be his pilot/passenger:

This figure is only available with the Optimus Prime bomber set, but I am wondering if the single unit is available for purchase second-hand or used.
Does anyone have any information on if I can purchase her separately this way?
