There are a lot of companies which supply (and fit) custom vinyl wraps for virtually anything (mostly cars). I don't see why they couldn't do a set of limbs - should be able to wrap the limbs, stabs and riser as a colour matched set.
Look at the 3M UK site for details of vehicle vinyl wraps and they have a free search function for local wrappers - one of these may be able to do the bow with off cuts.

Added bonus is wraps can be removed if/when your daughter decides to sell on her existing kit as she improves & upgrades.
