No. You should never put GFIs in series. Besides, that would trip instantly. A 120V GFI compares neutral current to hot current. If they differ by more than 5mA , it trips. A 240V circuit doesn't use a neutral. You would use a 240V double pole GFCI/breaker. It compares the L1 current to the L2 current. If they differ it trips.
