That's a big problem with PGP, so before you go experimenting first backup your key. When I tried editing an aka on mine (my email address had changed) I lost other people's signatures on my key. :-(
This makes sense.. A signature is a binding between a key and a userID. If you remove that userID, then clearly the signatures binding that userID to the key should be removed as well, since otherwise they are binding nothing. What should be available (although it is not implemented) is a userID revocation, where you can basically send out a messages that will remove userIDs from a key. Then again, signature revocations should be implemented as well...
