Realistically, if the Ivy league schools decided to play with the big boys. Could they?

Let's assume the ivy league schools(Harvard, Yale, Princeton, etc) decided they care about FBS football and they want to dump resources into being competitive.

Could they? Given their rich alumni base, connections on wall street and in Washington DC, and their large financial endowments.

Assuming they'd also just say "if you're a student athlete, just maintain a 2.0 GPA and you're good"

I'd imagine throwing 13 mil at a 5 star like Bryce Underwood would be chump change for Harvard.
