This is the volunteer DIY help forum. We don't do anything but advise you how to do it yourself.
Study the guide and notes linked at right (not just look them over). If you feel capable of completely dismantling and then reassembling your laptop yes you can change the cases (covers). Only you can determine if it is worth the cost and effort. Before you proceed purchase the recommended tools (every job is easier when you use the right tools)
A workaround would be to put covers on the unit.
If this answer is acceptable please remember to return and mark it accepted.
