As someone who knows a LOT about this (my NDAs are still in effect in places) let me just say -- you don't want this.
For one thing, ALL of these hair plugins are designed around fibermesh type hair (they may or may not actually BE fibermesh as defined by Daz, but the idea is the same). These don't animate well unless you are using a hair shader type of which iClone doesn't have (and thus you couldn't use them at all) OR you'd have to export the individual fibers (which is hugely computational intensive as well as looks crappy. IMHO).
The only/best hair for iClone is polygonal hair, and this is exceedingly hard to create. Worse, it's almost impossible to design a tool to do it. Blender has one such add-on and it's the closest I've found and although I've used it successfully frankly it's such a PITA and time consuming to do this it's just easier to use what someone else has done (as said above) -- there is plenty of Daz hair out there to satisfy even the most demanding.
Making such a plugin for CC3 would be both a waste of the devs time as well as someone no one would ever use, so it won't happen. Ever. You can take that to the bank.
(Now, if iClone could ever use a hair shader, some of which are even native to the nVidia cards... that would be a game changer).
