More to the point: Once the session is gone either active protection
of the SP kicks in (if used) or you end up at the resource unauthenticated.

Once a new session is initiated the standard SSO flow begins and a new
session gets established (whether that involves attribute queries or
not is immaterial here), replacing whatever was there before wholesale.

So I don't think the existing architecture can do what you want.
