Also, in order for Sans to predict Frisk's journey, he had to have gone on that journey as well.

How did he figure out that Frisk would arrive, as a human, in 2XXX (not 201X, placeholder year), when he himself arrived already as Sans? How did he predict exactly where Frisk would baldy need food (as you claim), if he never had to deal with this problem, being disguised as a monster the whole time?

The whole "I know what he'll do because I loves it" thing breaks down when you see just how different the Alpha and Beta timelines really are.

It doesn't make sense for Sans to have not made the original journey as FRISK, prior to his diguise.. If Sans really is Frisk, of course.
