The most difficult part in your setup is to make untraceable the VPN you run after going through Tor. The problem is: if you believe this VPN is safe / untraceable enough, why do you even use Tor in the first place ?

The problem is that you, at some point, pay the VPN, and that is very likely to be linked to your real identity somehow.

Paying for the VPN anonymously is possible with Bitcoin.

The reason you tunnel it all through tor is because you can't trust the VPN not to fold if the government subpoenas them. So if the data center hosting the VPN is subpoena all they can hand over are logs of tor exit nodes. If you didn't use tor, they would get your home IP and the jig is up.
