Hey, i'm also trying to emulate Lage's Benfica, and i did this:
I put some PI's
SK: none
Defenders: none
CM (Su) and (De) (Possibility to put replace the CM (De) by a DLP (De) or BWM - (De) - this one's for Fejsa): Hold positon, Shoot less often, and Drible Less + For the CM - Su: Stay wider (and eventualy pass it shorter for one of them to calm the game ?)
IF: Get further forward, Roam from positions, and Sit narrower
AP and F9: None (Maybe More urgent Pressing intensity ?)
AF: Pass it shorter and Take fewer risks (Maybe More urgent Pressing intensity
