Not sure if you're serious or not, but I'll indulge you anyway. Rohan Dennis, Jack Bobridge and Matthias Brandle set 51.8, 51.3 and 52.4km respectively, back in 2014/15, while all three were at the age of 24. Whatever time you set will be a record and you will hold it for as long as it takes for someone else to set what will probably be a significantly quicker time.
As far as I'm aware though, your weekly training hours are somewhat low and you haven't even ridden a fixed wheel bike on an indoor track yet, (let alone a pursuit bike), so I can't help feeling you are getting a bit ahead of yourself.
