I don't see any point in cooperation between CHL and KHL. Their ambitions are in completely different directions. The CHL wants to create profit for the clubs, while the KHL wants to create an empire.
Having a few European KHL clubs in CHL could increase the profit for the CHL clubs, but with Asian KHL clubs the costs would probably be too high.
And from KHL:s point of view, the CHL is only a rival. If a KHL team wins the CHL, the KHL wouldn't gain much from it, but if they lose, it would look bad for the KHL.
This. Sure, the KHL is aiming to make profit and it will take some time, but I believe it's better for them to focus on their own product at the moment. The best way to go would be to bring back the Victoria Cup, either with the CHL and KHL champion, or spice it up with the Stanley Cup champion as well. I don't see how the KHL could fit in CHL in their calendar either, since they barely got time for the EHT.
