Galaxy Note 2 with an AT&T Nano Sim?

Hi all, I'm currently an iPhone 5 user on AT&T but I'm very seriously considering taking the Android plunge with the Galaxy Note 2. What I would like to do is use my current nano sim from my iPhone and swap back and forth to and from the Galaxy Note 2 unlocked version. Is this possible using a nano sim to micro sim adapter? I'd really like to use both phones without adding another line of service to my plan. Has anyone had a similar experience? Thanks!
