Single IPv6 stack in the home is achievable today. Single IPv6 stack in the enterprise is achievable today. Single IPv6 stack in the access network is achievable today. This is how most phones work today. The node if it needs to talk to an IPv4 server uses one of the forms of IPv4AAS. Most probably 464XLAT. There are billions of devices that do that today.
Today if you attend conferences your IPv4 address is most probably 192.0.0.1 if they support IPv6-mostly (IPv4 option 108) and you have an up to date OS. Enabling IPv6-mostly on the access network will allow your IPv4 lease load to drop as CPE start to support it. The hard part will be turning down the IPv4 connections to your peers when the rest of the world has switched to IPv6.
