Ghost,

The first thing that came to mind when I viewed the images of your Design #1 is "Rack Rocket"

I realize your design wasn't intended for multi-staging but it certainly resembles the rack rocket concept. Ken Good the president of Tripoli wrote a fantastic article about rack rockets and you may find some of this article helpful because some of the designs mentioned also used metallic tape to overcome the obvious problems with a very similar type of design.

They flew one rack rocket on two FSI F100's and an F7 as the third stage motor!

I have a RockSim file on one of my back ups for my rack rocket design and I'm trying to locate it for you. IIRC my design used a rack of 24mm Estes D12 booster motors with an E9 on top.
