This is late but maybe will help someone.
These remind me of several movements from qigong series called 8 Pieces of the Brocade.
Over the years I’ve learned different variations of it from several instructors. That being said, some of the energetics you propose are new to me - most instructors teach qigong and tai chi as purely physical movements (which is why I study occult) anyway, so not surprising.
Your 2nd move reminds me of “shake the tail” which I always felt didn’t quite fit into 8 pieces, but drawing energy from the ground is genius- I can’t believe this never occurred to me there. Makes me want to revisit it focusing on your posted energy and visualizations. Thanks for posting!
So at the end of 8 pieces is “bounce the toes” - a very Yin exercise to get rid of energy imbalances after the series. You can google it. I believe it’s at the end for the same reasons for your warnings - you are building energy which you want to even out. I bet it would work well here.
