I really wish you'd give up with this idea.
If anything your idea makes us predictable as teams will read which side we consistently attack down and just flood that area.
We need, as other have highlighted above, a disciplined midfield of 3 where midfielders know when to tuck in to allow the full back to go forward on each side. Wingers on either side of a 3 up front is pivotal, and the only way to fit in a less mobile player is to play 3 at the back, which i think will happen from time to time - allowing the 3 up top to play narrower.
We need players who understand when to press and when not to. Players who will follow a signal from another player to initiate the press. We need mobile centre halves who can intercept a high ball.
