It's been discussed many times in the past, and while some parts are compatible, most would argue that it's not worth it to sacrifice a Phantom towards building another larger quad or hex.
the NAZA inside would work,. same with the motors and the rx- but the ESC's and GPS are specifically made for the Phantom (they're bare electronics), so wouldn't really be ideal.
You're probably better off buying a F550 (or F450) kit really. But even then ,. those would get you only about 10-12 minutes of flight time.
8 minutes isn't too bad,. but if you're really just looking for longer flights, look into all the modifications people do to add larger batteries to a P1,. and switch to the new Vision style props.
