Yes, we can possibly double it up for this. I know what you mean. Typically, it's common practice to put one set of navigation controls "above the fold", and one "below the fold". "The fold" is the part of the page that you see WITHOUT scrolling.
There are some cross-issues involved with this. Doubling up on navigation adds page load time, bandwidth, some confusion, etc. But it doesn't mean we can't do it.
