The primary challenge when adding CC to an ability is making it readable. I can't really think of any reasonable way to implement Busy Hands into any kit without making it's effect VERY opaque, but it could potentially be quite cool. Freeze and sleep, however, would be too similar to stun, and would be confusing to play around. Also, the entire idea of some CC being reduce/removable and some not is detrimental to the readability of CC in general.
