Would Greek Cypriots accept the return of the north of Cyprus if the Turkish Cypriots were expelled?

I’ll second Spyros Theodoritsis. Yes, Greek Cypriots killed Turkish Cypriots in Cyprus in intercommunity violence. Yes, there was de facto partition of the island since 1963. Yes, if you talk to at least some Greek Cypriots for long enough (as I did with my uncle there), you’ll work out that despite their professed desire for a reunified Cyprus (as long as the mainland Turks go away), they don’t necessarily have a lot of respect for Turkish Cypriots.

But no, making Cyprus Türkenrein has never been a talking point for Greek Cypriots. They do want their homes back, as you’ve clarified the question, OP, but they do actually want reunification and peace as well. I don’t think they’d trust any population exchange solution to resolve anything anyway: it’s a cause of Turkish resentment just waiting to happen.

Although it has to be said, the newer generation of Greek Cypriots has gotten quite used to living with partition; and reunification is no longer for Greek Cypriots an existential question, the way it has been for Turkish Cypriots.
