The recent update that moved Google Voice into Hangouts [1] has made that a reality for me. My phone took a swim a week ago and so I've been using a Nexus 7 as a temporary phone.

The only thing missing is that I had to set up my launcher, install all the apps again, configure my IMAP email client, and configure some third-party apps that didn't sync notification sounds.

[1]: In case you're not familiar, it added the ability to make and receive VoIP calls.
