Imagine those bulkheads as being 1.5" long BC-5 ogive nose cones, cut down and shaped to conform to the ST-13 tube. Also, those ST-5 tubes are cut down their lengths to be glued up against the ST-13 tube...
Length: 23.3"
Diameter: 1.34" (ST-13 / BT-56)
Weight: 3.47 oz

Enjoy!

Now that's creative. Very cool Craig! 
I saved your Challenger III 2-stage file as well. You have a 2.5" bulkhead thickness/length with about 1.5" exposed in the design file. Would a Semroc BC-514 or BC-517 work or is that what you had in mind? Those are 1.4 and 1.7" exposed length plus whatever the shoulders are.
I was going to add the molded launch lug into the fin can subassembly later tonight and I noticed you already did that ..... thanks! Now I can save that subassembly with my other design files. I hate having to move all those individual components around.
