I've seen players (my next opponent actually) put the DR/DL right in the middle of the where the DC and DMC blocks intercept it (the center of the DR/DL block). Sort of like a balanced Attack and defend role. When you have a wingback (DMR/DML), this player is counted as part of the mid, in reality they even sometimes run into mid with the ball. I have seen some count a back 3 with 2 wingbacks as a back 5, since when defending that's what they look like, a back 5.
Most of what you said is just in theory but there is absolutely no proof. A lot of us are having problems where MC are playing as wingers and so on.
