Nothing will break. Like you say they are virtual and contain no code
and deploy nothing. So your system will continue to function as it
currently does, and Portage will sort itself out when you next emerge world.

Unless of course portage wants to unmerge any of the providers that
satisfy the virtuals, and you say "yes" ... :-)
