I don't think this is helpful. Crossfit appears to prioritize speed and # of reps above all else, and is notorious for people doing difficult exercises with terrible form to try to hit those targets. HIIT certainly emphasises intensity of effort and prefers relatively short rest periods between sets, but not at the expense of proper form. eg when I think of cross-fit weight training or callisthenics I think of lots of snatching and jerking, with HIIT I think of moving slowly with form and trying to hold tension at the apex of the movement.

If you want to do Super Slow, great, but that is the original HIT, High Intensity (Strength) Training from Arthur Jones of Nautilus fame. I just went to YouTube and searched for HIIT. I don't see any videos of "moving slowly with form" (which is exactly what Super Slow is built around - 10 seconds concentric, 10 seconds eccentric, one set to failure).
