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.
Sorry about your phone. Yeah I'm aware, the signs of this trend are all around. Interesting how hangouts has become a unified communication hub. Close to hitting mainstream IMO.
