This is a very clever and interesting exercise. I'm typing on a little telephone screen and it would take me a week to explain my reasoning, so I can only give my proposed answer. It's . . . 60 degrees above the horizon.

The angle of projection that results in the minimum velocity being double the maximum velocity of a projectile is approximately 63.4 degrees. This angle leads to the desired relationship between the minimum and maximum velocities during its flight. The calculation is derived from the relationships of the velocities in projectile motion.
