Okay I have a 60 x 80 opening that I want to put a set of french opening doors in.

The one that will work perfectly at home depot (and is pre-hung) is this one:

But it has friggin windows in it.

I would like one that is like the study on my first floor has (basically a left hand and a right hand with locking hardware like the door up above).
Can't I just go to HD and get two identical (left and right hand ) pre-hung doors and combine them?
