No. It wouldn't be very practical, nor very useful. The overlap between people who could self-host it (node.js data collectors, Redis caches, EC2 and Aurora instances, background workers, etc) and whose analytics requirements aren't more advanced than what it offers, is probably nonexistent. There's already a bunch of good self-hosted options out there.
Well, fwiw there is no well-designed and useful self-hosted analytics solution out there at the moment. Piwik is useful but not exactly a pinnacle of good design. Pretty, but inconvenient. Mint is well-designed, but functionally it's next to useless for anything outside of basic vanity metrics (I used it extensively, have three licenses). So there is a niche. Though I hear you on not wanting to deal with related support issues.
