Estes Mystery Parts Design Guess

From the Estes website, here's the parts that were shown for the upcoming Nike Smoke kit.

There's a lot of centering rings, two shrouds and an Honest John style nose cone. I assume that's the Mini Honest John nose cone.
There are three crescent shaped pieces that might fit the end of a tapered body tube piece.
Three trapezoid pieces could fit between the two tapered shrouds.

I played with the pictured pieces. Finding a place for all the centering rings was the challenge. Eight centering rings might be used to join the three tubes together. The upper cutaway drawing shows some of the centering rings.

The low end tube looks like a BT-60, the smaller tube in the center taper area is a 50, the upper overlapping tube is a 55.
Having the nose cone sit farther into a 55 tube would cover up the spin motors molded into the low end.
The tapered and capped outside tubes are cut from the second BT-55.

The fin grain dictates the shape position.

That forward tube has to be longer than what I drew. I'm probably WAY off.
Looking at this guess, I hope so!
