From a legal point of view is it okay? Not talking about aircraft capability.
One more time...
From a legal/practical/defending your decision and ticket if you mess it up point of view, WHY WOULD YOU DO IT IN THE FIRST PLACE?!?
There is NO justification I can think of that would give the Feds ANY REASON to do anything other than crucify you for a "reckless or careless" decision. In a critical phase of flight, intentionally doing something less safe than an accepted standard, thereby putting your passengers or the public at higher risk, is certainly within MY definition of reckless!
