By 'not standalone', I assume you mean "this profile does not work by itself, 
and is only meant to be inherited by other profiles". If that's not what you 
meant, we also need something that does that :)

Doing this will break portage for people who are using "old cascaded profiles". 
Portage would freak out if there wasn't a profile where there was one before, 
and there wouldn't be a way to do a 'deprecated' file to tell them about the new 
ones.

I can't really comment on the structure, since I don't really do much with 
profiles myself (no gentoo-x86 commit access).

Not necessary. It can just be a separate directory tree under profiles/ much 
like default-linux/ was created for cascaded profiles originally, and they can 
all be marked as deprecated or something.
