I don't see it. Harvard and the Ivies don't even give scholarships. Their megabucks donors don't have any motivation to see their sports in competition wit the P-5's. They make donations for chairs of departments like international political strategies, medicine, law etc. Even Stanford & Cal who have played the P-5 game doesn't have many athletic donors.Consider
Harvard, Penn, Duke and all those small colleges that focus on law, doctors, etc with a high ratio of graduating superior earners realizing what their deep pocket alumni's could do to affect NIL.
So far we have yet to see this impact,,,but consider how impossible it will be to compete with them it will be if they wise up and take advantage of their graduates/alumni/boosters...Then it will get messy (er)
Sports are minor matters to the donors to those schools.
