Maybe it's just me ... but I wouldn't trust the isolation to be good.
Apart from on-die coupling, they share the same power/ground leads, however
short they are.  So just getting power and ground from the board onto the
die, they would be corrupted by what happens in the other gate and its load
(L*di/dt).
