You will need a lot more tail than that to keep that nose up. You have an extra 30 inches forward of the mast to balance out. That 30 inches includes about 50 gallons of fuel, up to 3 extra people, and a 30 inch greater forward arm for the cockpit.
I think it would look better with the new style end plates instead of the old D style. Probably need the vertical of the AH-6M and the canted tail-rotor too.
