Sirrusa has a special tag set which causes it to buy back any outfit that the player has, whether it is sold there or not. The idea is so that if, for example, you capture a ship that has technology not available in your storyline, you aren't stuck with useless items you can’t get rid of. But I’m afraid this feature can’t be extended to produce the behaviour you’re looking for.
