The Aogiri Tree has been one of Dr. Kanou's most reliable clients. However, Kanou will eventually require more help if he wants to continue developing new ghoul based experiments, especially since the majority of them have been eliminated. Furuta's help won't suffice so after Aogiri is gone, who will Kanou cooperate with?
Answer: Clowns
The Clowns have already indirectly received support from Kanou: Ganbo. Furuta probably introduced Ganbo to the Pierrot.
He resembles the incomplete ghouls/failed experiments from part 1.
More disabled ghouls: They tend to be abnormally larger and slightly retarded with a few exceptions. As Tsukiyama describes, Madam A's ghouls were mutant and hypertrophied.
With Shirazu's Quinx insight, Kanou's new hybrids will be very versatile weapons against V and the ones who will take advantage of them will be the Clowns. By the end of TG, Kanou will be capable of mass producing these perfected new-gen one-eyed Clowns.
tl;dr Kanou will provide a major supply of next-gen one-eyed ghouls to the Clowns. The masks have already been reserved for this epic event.
