Most of your non-consumer wishes already came to fruition. The original smokey sam was in effect a nozzle less motor. It had a casing but it was weak. Spiral wound phenolic treated tubing. It had a foam nose cone and tail unit. Dirt cheap. Vulcan was one of the vendors. I think Navy was the primary user.

Our nozzle less motor had two parts:

1. Casing
2. Propellant

Like an A10-0T it used propellant as the bulkhead and the near zero thrust on the bulkhead burn acted as a delay. They were all about 2-3 second effective delays.

If you have a heavy 13mm motor rocket you can use a A10-0T with a 1/8-1/4g ejection charge added with a paper cap inserted with the rear of an x-acto knife. I suggest 3G or 4G BP. It is easier to dispense it volumetrically than by scale.

The propellant it used is not listed on the U.S. Rockets "reads" page.
