What's the goal? To have a private exit that only you can use? There is this very interesting paper and project called HebTor: https://dl.acm.org/doi/10.1145/3372297.3417245 This paper introduces HebTor, a new and robust architecture for exit bridges---short-lived proxies that serve as alternative egress points for Tor. A key insight of HebTor is that exit bridges can operate as Tor onion services, allowing any device that can create outbound TCP connections to serve as an exit bridge, regardless of the presence of NATs and/or firewalls. HebTor employs a micropayment system that compensates exit bridge operators for their services, and a privacy-preserving reputation scheme that prevents freeloading. We show that HebTor effectively thwarts server-side blocking of Tor, and we describe the security, privacy, and legal implications of our design. If you're interested on playing with it -- for educational purposes only --, I can share some instructions in private. Gus -- The Tor Project Community Team Lead
