Why not O-line "specialists"

Teams already bring in different defensive backs, linebackers, and d-linemen.  Offenses bring in extra WRs and/or different RBs.  So why not different O-line packages for passing downs?

I keep hearing that some of our O-linemen are better run blockers while others are better pass blockers.  So we need to come up with a rotation that gets the most/best use of every player.

The problem is, it wouldn't take long for other teams to know that when we bring in so-and-so, that means we're about to run or pass.
