I tried in the past to run multiples the way you are describing but always had the upper minnow get tangled up or hooked on the side of the hole when I had a fish on the bottom hook. I still run 2 hooks w/ around 2-3ft of leader line but in this config. Bottom hook, 4"-6", split shot (size depends on bait size), another 8"-12", second hook tied to main line with palomar knot, another 12" of leader, swivel and then tip-up line.
