Some people have done this but I personally do not. Detritus will get down in there and it gets very difficult to remove, sand sifters have a tough time getting to it there as well. Lots of people place live rock directly on the bottom in a bare bottom setup with no problem, I like to spread a layer of sugar fine sand, then a coarse layer on top to prevent any pressure points on the glass.
