Agreed with Missy. Aurora is $160 in stock at PS, so her full stock would go for around $65 (40% of total cost). If it's just the bits and pieces but not her dress/outfit or shoes, then yeah, you could get up to $40 for the kit.
Keep in mind, though, that if you ever want to sell your Aurora (not that you would!), you'll be selling her with incomplete stock. That does decrease what you can ask for her, but by approximately the same amount (usually) that her stock sells for. That shouldn't make or break your decision, but it's just something to think about.
If you are okay with that, then go forth and list it, my friend!
