I would say don't do this.  You are likely to experience software defects that are unique to this configuration which IMHO is far less common than a peer per v4/v6 transport.  It will also show they aren't doing any 'kinky' engineering to get you IPv6.  While some folks may disagree, the ability to connect you to an edge device that does dual-stack will provide you better service.
