I think that you should be able to trade in an unlock for another. Just in case you are me and unlock something that you didn't want.
then all you'd really need would be one unlock. want to be medic today? sure, go for the medic unlock..support tomorrow? get the support unlock.
kind of defeats the purpose of getting all the unlocks.

Well, I should have been more specific. Maybe only allow two changes for each unlock. That way it doesn't defeat the purpose really and you can choose the gun best for you.
