You'd have to be pretty keen to move those components over as they're pretty much bargain bin parts. I'd suggest selling the bike and putting the money towards a mans bike, or giving the bike back to your sister and saving up for a new bike. I really can't think of anywhere that sells frames on their own that would be cheap enough to make it worthwhile.
