I have to admit two things: One, I don't know a lot about the 3-4 defense and secondly, I'm intrigued by the thought of it.
What I do believe is that Wooten and Peppers are big and athletic enough to play 3-4 ends while I have reservations about Paea playing any role at his size / athletic ability. That's not saying he can't add girth to play the nose. I like McClellin and Bostic on the outside utilizing their speed Briggs and Williams look to be a fit in the middle, as they are surer tacklers and range and explosiveness not what it used to be. Not sure Green fits in this scheme unless he can move inside.
In the secondary, I would really love to see Tillman move to safety or let him walk. He is simply a funnel corner and a liability if left alone. He's still a great tackler and very instinctive. I could multiple strips and picks for him next year. I like us to sign Jennings. He is a really good cover corner. Imagine the confidence he would have knowing Peanut has his back. I may be alone here but I think Conte is redeemable next year. He was better in 2012. Was his regression due to scheme and coaching or ability. Wright can go. He simply doesn't make enough plays for his aggressive nature.
