Sample size is indeed very small but bb/100 is surely good enough. Don't know about your bankroll but why not give it a try.
Stats are a bit nitty though. And gives the tight range you play I think you could be more aggressive. Don't think that will be much of an issue at 5NL still though, but something to look into.
Just give it a try and be prepared to step back if it doesn't work out. No clue what a decent winrate at 2NL is though but if you can keep this up you can consider this crushing it imo
