If you are asking whether it is feasible for someone to make a device
that is capable of doing this while ignoring the protocol requirements,
then yes, that could be done. Obviously, it would result in issues with
two devices potentially reacting to frames at the same time. Anyway, I'm
not sure I understand what exactly you are asking for here.
