Replying to Binding mounting and brake width question

I recently purchased a pair of used line Mr pollards opus that I believe were mounted at recommended with salomon sth driver 14s. My question is first off can I mount a pair of drivers in the same spot? Or do I have to use a different pair of bindings if I want to mount at recommended. Another question I have is would the Rossi axial2 xxl's be a good alternative to the drivers? Thank you for the help. I'm quite new to skiing.
