Assuming that you want to use your own domain as the user supplied login identifier --

1. Go to https://stackoverflow.com/users/login-add?returnUrl=%2Fusers%2Fcurrent and Add a login using Google. This will add Google OpenID Connect identifier to your account.
2. Host OpenID Connect discovery document at your domain (see http://openid.net/specs/openid-connect-discovery-1_0.html#URLSyntax for details.)
3. Wait till StackOverflow start supporting OpenID Connect discovery

In addition, if StackOverflow supports OpenID Connect Migration 1.0, and assuming that Google returns your custom domain claimed_id in the Migration response, then:

1. Host the JSON document as described in http://openid.net/specs/openid-connect-migration-1_0.html#VerifyOPAuthority in your domain.

would smooth your way.
