You won't be able to create an xdg_surface from not-xdg_shell because of
the single-factory principle, but with v6 it would theoretically be
possible to create an xdg_surface and assign it a role not defined in
xdg_shell.

No. xdg_shell will not work as a desktop environment component protocol.
It's targeted at toolkits and clients that act as regular clients.
