Never tried but I somehow doubt it. Standard issue UDP hole punching absolutely does work though. You still usually need hole punching with IPv6 if there's any kind of firewall in the way, but unlike IPv4 with NAT it's virtually 100% successful. Even if IPv6 NAT is deployed there's usually a 1:1 internal/external IP mapping making hole punching 100% successful.
