Has anyone tried this defense?

I have been messing around with some defenses online and I have come across an interesting scheme I think, or at least it has been having a lot of success so far. I call cover 6 out of the nickel but then put all the players on the cover 3 zone side in man and control the safety on the cover 2 side. Takes away everything to the cover 2 side, it's weak against drags to the side where your guys abandoned their zone but you have 2 deep men on them side who should be good tacklers
