I understand Barbara's point of view but what you suggest would send the wrong message to the team. Conte's philosophy is pretty plain and simple: we never start favoured, we win through maximum focus in every minute of every game.
If Conte changes starting defensive/offensive midfielders in regards to the opposing sides, it will have different impact on the players: opponents are good we must concentrate and not concede/ we are stronger we'll win because we are more technical. That's not how Conte works, he believes in win by concentration, motion and repetition therefore improvement of trained schemes.
Of course he recognizes the tactical strenght of players who can often win their duels or the importance of good feet but that's not at all his coaching style: he wants solidity, he wants his players to be under pressure in every circumstance indifferently versus any team.
(As example, Pirlo not only was favoured by Marchisio, Vidal, Pogba, all with great defensive capabilities, but Pirlo himself was often the player with the most kilometers covered during games, so no tackles no running back but steady sense of position.)
This is what brought Juventus league after league, one while being unbeated (23wins, 15 draws) and one setting the all-time points record (102), but it also was the main critique to Conte when Juventus dealt miserably with inferior teams in Champions league.
