Nope.

In their infinite(simal) wisdom the architects of IPv6 determined that
a host configured with both a global scope IPv6 address and an IPv4
address will attempt IPv6 in preference to IPv4. If you configure IPv6
on a LAN without first installing your IPv6 Internet connection, that
LAN will break horribly.

Work your way from the outside in: start with BGP, then the interior
routers and configure the LAN last.
