For those that are thinking of doing this, you should realize that EMI shielding serves two proposes. One is indeed reducing emissions from the device. The other is reducing the emissions from the environment which might affect high speed or otherwise sensitive circuits. The shields themselves weigh very little, and there is a risk that you'll damage the board trying to remove them too.
