Could you explain this yonko on the ankle? This sounds very interesting.
There is a ground lock from kotegaeshi that involves Uke being on his back when pinned. It comes directly out of the kotegaeshi employed in the Randori no Kata of Shodokan and can be seen here - http://www.ttac.0catch.com/tekubi.htm
When Uke is on his back it is relatively easy to try a front/soccer style kick towards Tori's head/chest/waist as he tries to turn Uke over or lock his wrist.
Because Tori is near Uke's head after completing the kotegaeshi, the kick if it does come, tends to be nicely extended, allowing Tori to easily time and trap the ankle to his hip using tegatana. This is of course only possible if Tori is maintaining zanshin and keeps the entire body of Uke in view/awareness. At this point Tori releases the other hand that is still holding the kotegaeshi and uses it to back up the sword like grip on Uke's ankle. From here the application of yonkyo (tekubi osae) is identical to when applied on the nerves on the inner arm, in this case however the pressure is on the nerves of the inner ankle.
As soon as this is effective, Tori can either pin by stepping on the inner ankle of Uke's other foot with the edge of his own foot (pressing the same point as the yonkyo on the leg against the floor) or maintain the yonkyo hold the leg and turn Uke over and place him on his stomach by straddling Uke's back and facing his legs (similar to a figure 4) and apply a leg lock.
The figure 4 type leg lock option came from my Jujutsu knowledge, but application of Yonkyo to the ankle has become a norm for me from Aikido alone. In our system, leg locks are applied as part of the Shodan grading syllabus and "other hand" knife attacks form a major part of the kyu grade syllabus. Maybe there is some historical or other reason why these techniques and attacks were placed into the grading system. Whatever the reason though, I guess Tomiki deemed them important enough to make them a major part of the basic syllabus.
Apologies for the length of this post.
