There's no problem with having a unique fingerprint. The problem is having a consistent one. Randomize the fingerprint every time and you're fine. The IP address problem applies to everyone, including anyone using tor browser. The only solution to that is not using your own IP address (VPN/proxy). If I were going to make a secure privacy focused browser it either wouldn't allow things like rendering SVGs (which have introduced vulnerabilities beyond tracking) and wouldn't allow much (if any) JS and only a sane subset of CSS.
