I'd be really curious to see a study of the performance of CS majors in later classes by paradigm of the language taught in CS1 (i.e. imperative/OOP vs functional). I've been trying to keep my eye out for a while, but haven't really found anything that answers this specifically.

Maybe course withdrawal rates could be used, but getting access to the necessary statistics seems like it'd be a chore. I just checked with my university and the only statistics I can find are centered around graduation rates. One would likely have to contact all the registrars among a sample of universities individually, as I haven't found a university offering these statistics yet.

CS Educators do this research all the time, but it's pretty challenging to design a CS1 class that's effective but also so radically different from the typical paradigm.

There's also a risk you'll set students back if it's not effective so there are definitely ethical concerns and it requires interrupting a professor's load for the quarter. That said, CS educators conduct research like this all the time and there's probably a lot of value in studying this kind of change.
