Sadly, this model won't work for Europe where tuition fees are very low already. I can give you an example with UK, where I did my bachelor at a top 10 university for roughly 10k GBP (i.e. 3k per year). My masters degree at a top 3 university was 6k and it lasted a single year.

Would you say that Europe is a target market for you? Have you thought about how you would tackle it?
