No. They want players capable of doing everything on their own, scoring and pulling team out of $#@! when it's needed. Mbappe can do that stuff. Belotti will never be able to do it simply because he's limited and a type of player that Luca Toni is. Sure, he might be able to score goals, but teams abroad nowadays would never want such players and there's no way they'd pay a similar amount they paid for Neymar, Bale, Ronaldo and now possibly Mbappe.
IMO it'd be horrible buying Belotti for 50mln, let alone double the amount. Such players can be shut down as you can always know what to expect from them. That would probably the worst move in the history of football transfers.
