It wouldn't be beneficial because most of the players we are talking about wouldn't come from the same development system. Think about it this way, would you make the point that an english descent raised in the US benefits from the same football culture than someone raised in England? That Rooney would 100% turn into a world class player if he was raised in Cleveland Ohio?
The USA today probably could produce 17-year-old Rooney. Lots of good players coming out from the States, and even Canada without having the level of talent Rooney had. Whether he would progress into mid-20s Rooney is a different question entirely.
That said, I don't really follow the point you're making with the Rooney example in connection with the question of whether European born players would improve African teams.
The point was that African players in Europe as they are now, being forced to play for their national teams would benefit those national teams because they would have a greater pool of quality players to choose from.
