I think you can't do it. The file is digitally signed. Any modification will be detected.

But you can try it and extract the RCData. This is a WIM file. Mount it and replace the bmp and commit it. Now try to replace the RC Data with your modified WIM and save the new dll.

But I don't think that this will work.
