My Boyos want a Delta IV Heavy. I've been toying with the idea of making an alternate top for the center Common Core - so we could easily have a Delta IV Medium.
While drawing it up, I thought to myself that it would be nifty to make it a real second stage, and finless would be extra cool.
So I bt50 based proof of principle - 13mm mount, 25g nose weight, card stock transition fairing.
The skirt has 4 holes punched in it, just above the level of the nozzle, which is very recessed.
Here's the 1/2A3 flight. Slo-mo

We followed Tim's 1st Law (if you get it back, the motor was too small) and lost it on the second flight. An A10. Flies straight enough to loose
