Ok im not really good with photoshop and i dont want to try it in paint lol...but here is my suggestion.

Since she wants to keep the kit maybe tell her to get everything re-painted (black if possible) with some pink lip w/ black center rims. A little bit of a drop, some tint, and a different wing if she really wants one. Some stock tails or smoke the ones she has and black housing headlights. Thats what I would do if I kept that kit.
