Pilot modelling within the cockpit?

[simast]

I am not sure if this would be the correct forum to discuss this, but I will give it a shot anyway:

Thus, the question, why no flight sim attempted to implement a pilot model within a cockpit so far? Is there a particular reason why this is avoided universally? The way I see it - the ability to see your virtual pilot (or co-pilot!) would add to the immersion greatly. I can't seem to think of a reason what could possible go wrong with adding pilot models. Sure the pilot legs would probably hide the pedals, but it should not affect other instruments. And the fact that your co-pilot can obscure right-side visibility is part of the "sim" factor, right?

Some other ideas:

- Pilot hands should be on a stick and properly animated. Heck, if this can be extended to other systems (such as throttle) it would be amazing!

- You could probably model injuries better, such as blood on pilot instead of your regular red tainted screen.

Maybe this is a good idea for a mod? Still, would like to hear your opinions on this.

p.s. First-person shooters are moving from this floating-camera approach also (you can see your body/legs in BF3).
