Sorry, that is already being done. There was a woman here many long years ago that did just that. She did make a fortune but ended up having to pay a lot of that back in legal fees when students were getting seriously hurt because of her "casual teaching styles" The kids however, loved her. Who doesn't like to hear they have "natural talent" and "excell way past most riders" even though they have only been on a horse a hand full of times. Man I didn't like that woman at all, so many people would go to her thinking she was a miracle trainer. Ugh!
It gets even better when there's more money, higher octane horses and high level competition in the mix.
I love the people who have a "great lessons" which consist of doing trick after trick after trick, and then SURPRISE the horse is dead lame within a year. And when they go to shows, the horse is not collected, connected or even round, the rider is pulling, half to stay on and half to control the horse. Then they show way above what they are capable of (but can do the tricks), and it's the judge's fault they couldn't crack 55% on their imported, quarter million dollar WB.
My favorite is Uta Graf's freestyle on Le Noir, she shows a collected walk, transition to piaffe, 15 perfect, clear steps, and then transition right into extended walk. That to me exemplifies what dressage training is about, not doing tricks. However it's always the coaches who allow their students to progress too fast to doing the tricks, or jumping, and praise them like there is no tomorrow that are the "best" and who everyone loves. The coaches who get results and push and don't give you freebies are the ones who are "mean" or "hard" and have only a few very dedicated students, but end up with the majority of prizes at the shows, and the accolades of the judges.
