I have thought of building something to drill 10 feet at a time, one row on 6" centers. This would mean mounting 20 drill spindles on a z axis on 6" centers(this would cover all the centers except 4" without removing drill bits)
Any ideas to help me?

Go with this. You know it works, the hand drills are an off-the-shelf item and everything else is easy to fabricate.
One modification might be to mount the drills in some manner to the spacing can be changed.
One additional suggestion is that when you buy the hand drills you get a lot of spares. You will have to get the mounting clamp for these custom made and it would be annoying to have a drill burn out and then find that model is not available.
