Yup. I'm sure someone already figured this out but didn't tell anyone (or I just missed it).
If you can make the skill "Dash" do it, you can make Counter Tackle do it, except I'm pretty sure it will only activate on the enemy.
I need to test it more to make sure, but so far I've made the animation change...
Edit: lulz. I made it use the Dark Sword formula. I don't know if it critical'd on the second time or what, but it caused knockback as well as MP absorption.
Edit2: Definitely was a critical hit.
