As far as Sema goes, I don't see why you wouldn't be allowed to do it.  
Neither GCC or EDG (or clang) complain about it.

Nope - The subsitution rule explicitly states that std should only be  
substituted when it's a namespace in the global scope, so

class std {
	void foo();
};

isn't substituted either.

Nope.
