Don't be ridiculous. Even if the seat was the wrong shape, the worst that would happen is the airbag inflates and breaks the side window. Or you just don't worry about wiring it in when you install the seat.
Well, how about this to consider. If the insurance company finds out you had a non-standard seat installed, they may refuse your claim, or not cover part of the repair or personal injury. You could sue them, but the case would not be strong. There are some things I don't mess around with, one of which is the safety systems. I consider the seat, with its custom design for the car, and airbag configuration (especially when they are in the seat itself) and even how the seat belt fits, to be a critical safety system.
At a very basic level, to me it isn't worth risking any potential injury, regardless of how small the risk appears to the eye. Ford carefully designs the entire system as a whole, and crash testing is done on only that configuration.
I agree it could probably work. But I would not wire up those airbags - and the car most likely will post an airbag alarm if you don't, or perhaps it senses certain characteristics of the airbags. I don't know. But I personally would not risk it.
