Great !
For short lived connections (DNS, web), this could be true.
You don't use outbound SSH and SSL tunnels, or other long lived connections?

Me too. For IPv4, there is no real alternative.
The asymmetric tunnel is no issue. If you tunnel back, it brings overhead only.
With IPv6, there is no napt problem. But firewalls & ingress filters can introduce same problems, so sticking to same gw for single connection is a good thing. So my long term vision: use IPv6, prefixes of to_be_used gw and use source address routing to that gw if destination is not inside. IETF HOMENET moves towards this idea also.

This is something different.
