The way I'm designing my future curriculum, this would probably work. The first thing I want to teach is escapes instead of reversals. Then I want to focus on the control, submissions will come later.
The way my Master teaches, it's mostly rote memorized. The Taekwondo class (which we were in) leans heavier on memorization than the Hapkido, although it's still important there. This is one major area where I disagree with the way we teach. (Of course, the fact hat I've learned it well might prove myself wrong on that).
And for now, I do have to teach my Master's curriculum his way. Or at least, mostly his way.
Its not a binary decision... teaching the entry, control, structure breaking, off balancing or teaching the rote memorized pattern focusing on the specific finish.
As an example, lets talk about kote gaeshi, katate tori or as you call it v-lock (if I remember your explanations right) Youtube will show you kote gaeshi or if you look up danzan ryu you will find it as katate tori. Anyway, a common kata / form / drill for this would be to have the other guy reach for you, with his right hand. You get off line, parry and blend with your left hand, catching his hand - your thumb on the back of his hand, your fingers wrapped around his thumb. You then rotate and bend the wrist into the lock. You would not have to change anything in that drill, to focus on the structure break, off balancing or maintaining control. Only what you emphasize.
As you parry and blend with the reach, you add some force to his reach, continuing it a little further than he intended. This off balances him a little and starts to break his structure. From this point on, the goal is to never let him regain that structure or balance. As you catch the hand and establish your grip, his balance should further break and his structure weaken more. One key here is to never let his hand return to his structure... it should always be just a little further out than he wants. His hand should be separated from his body and connected to your body, and you should have proper structure and balance. A slight bend in your knees to lower your center, should also lower his hand, off balancing him more, further weakening his structure. The rotation of the wrist into the V-position, should happen because your center is rotating. When you initially blended with the reach, you extended that reach beyond where he wanted it. This put a little tension in the arm. This tension needs to be maintained through out the technique. Humans can only resist in one direction at a time. The tension is a pull that keeps him off balance and his structure broken. Your body rotation is a second direction for him to deal with. He can't resist both at the same time. You then add an extension, in the right direction with your thumb... this is a third direction. In addition, when he reached and you blended with the reach, you should have moved his hand off his center line, thus making it weaker. Throughout the rest of the technique, his hand should be moving further away from that center line. If all this is done correctly, you can apply one of many finishes. Sure, do the one you were supposed to memorize.... but at this point you should have control of the other guy so much that you could do any number of finishes. If he was supposed to tap and he doesn't, it should not take much to help him realize how vulnerable a position he is in... without adding force to the wrist. The best part is that you did not have to change the drill, the order or the memorization. Also, if you emphasize and work on the off balancing, structure breaking and control parts... the finish you are trying to get will be much easier.
I would be interested to see your drill for this lock. What is the set up and entry, what is the finish you are looking for? I would bet that we can find off balancing, structure breaking and control in your drill for this technique.
