My guess is that you'll get a "safe" flight, but not an interesting one as far as the video goes.

I have launched my Oracle on a D12-3, D12-5, and D12-7.

The D12-7 was by far the best, as the boost phase was longest. The descent phase portion of the video, on any of these motors, tends to be a scramble of images as the camera swings around.

I suspect ejection would be at apogee for a non-existent D12-6. A C11-3 might eject near apogee.

Also, the camera (with rocket body attached by a long shock cord) survived a descent, onto a field of freshly turned over dirt, without a parachute. THAT made for an interesting descent phase!
