the only thing i would think that might make things difficult is if you were using recessive morphs, and so you have a bunch of hets, and get rid of the parents. know if you were to try and sell one of the hets you wouldn't be able to show potential buyers the parents. i know if i am going to buy a het ghost from some one, i better see the ghost that they own. gets kinda fishy when you have a bunch of hets but no morphs.
i saw you were going to be working with a ghost, so i thought i would just throw that in there. but the rest of your plan sounded like what alot of people do.
