It is still not a transfer that has happened but I think (if it happens) it would be a wrong transfer. PSG already has Barcola and Dembele, what would they do by buying Kvara?
These are players with the same characteristics and there are already 2 players with those characteristics in the team. Kvara is a young player, if PSG wants to polish him and sell him for a higher price like Mbappe after some time, then it can happen, but Napoli would not sell such a player cheaply anyway.
Why would Napoli ruin the chemistry of the team by selling a player while they are heading towards the championship? It is not a transfer that will happen in the mid-season transfer period, I think it will happen at the end of the year.
Kvara could be a complement to PSG's strength because even though they already have Barcola and Dembele, PSG needs one more player, this aims to ensure that the players continue to show their consistency and usually when a club has competition it will improve the individual quality of the players. Luis Enrique also has many options when he wants to rotate and they have the opportunity to compete in several competitions that they participate in with different strategies.
In addition, they need to improve the midfield so that PSG can try to dominate when playing because what makes PSG difficult is not talking about Ligue 1 but the competition in the Champions League. Likewise, Napoli and they sold Kvara because they had other players in that position so the coach tried to optimize the efficiency of the players.
