Careful the cylinder (D) for model 1 is not perpendicular to the cone (SD) Probably better to maintain the height of the cone greater than 1/3 but less than 1/2 the diameter of the cylinder though. Overall Model 2 looks most promising as an interesting Final model if you levitate the sphere (SO) slightly above the base as indicated. Good job with the 2D Sketch Analysis!
