In the short term, I think Lukaku can still be relied on. We have never doubted his sharpness when buying clubs in Serie A. but in the long term it is clear that bringing in Lukaku is not the right thing. Meanwhile, Osimhen is a player who can still develop. He can reach another peak at his current age. So it can be said that Osimhen is very suitable for the long term. But Osimhen really needs new experience at a new club and I hope he makes it to PSG. But the problem is still complicated at the moment. And there has been no progress at all. Meanwhile, Napoli seems to have started discussions regarding Lukaku with Chelsea. The Chelsea club owner definitely wants to fulfill Conte's wish to bring in Lukaku.
Osimhen is a player who will progress, and has many seasons ahead of him, and Lukaku will most likely soon think about ending his career, or about a transfer to Saudi Arabia, by the way, he speaks very flatteringly about this champion. Therefore, exchanging Osimhen for Lukaku would not be the best decision for Napoli, unless they could sell Osimhen for the money they want to get for him, and buy Lukaku for much less money, because as we can see, Lukaku's market value is not that high now.
