If the coverage and wifi integration was as good as Google Fi and my girlfriend and I can use our Nexus 5 phones, I would definitely do it right now. I would also pay a decent premium over our $35 a month unlimited call/text, $10 Gig data plan.

The easy international hookup feature of Google fi I could give up, although that is pretty sweet. All over Europe my phone would hook up automagically with the local system about 30min after my plane landed.
