I second in saying Go for it.
But like joepythons said, don't expect to change a whole lot there, they have their "policy". So like I said you probably wont be able to change a whole lot, but you will be able to take better care of the reptile with what you have to work with. Plus you will be able to give out much better care info to possible new owners than just their rediculous caresheets.
