There is no problem with this from the crypto or GnuPG/OpenPGP or keyserver perspective. They don't care what the user ID field is, and whether it contains a name, an email address, or both.
But: as you note, this can be a problem for some email clients, which tend to try and locate keys via an email address in the user ID field. If you're willing to forego that piece of functionality, then it generally can be made to work via manual configuration for that key.
