First, you have to consider the context in which she mentioned Melody at the time, she was the eccentric and edgy gaijin that didn't know much about the industry and took advantage of it to get away with certain things that wouldn't normally fly if people thought she knew more about the industry and the language at the time, she has mentioned this a few times.
She did it as Coco, which allows her to detach from her real self, a collab between a virtual ahem... girl and a Yakuza dragon can actually work, probably the same way it worked on her first collab with Polka with that bomb defusal game, by that i mean the setting, she was eating and getting drunk at a hostess club and being bothered by Polka on the phone.
Even when using her Koikatsu model it's based on herself, the "line" isn't as blurred, i can't really imagine kson collabing with Melody, it's not really the kind of content she makes.
Oh and i wouldn't put so much weight on their supposed friendship, Coco calls anyone she messages a few times on discord a friend.
I'm not saying it can't happen, in fact i can see Coco caving in after getting nearly stalked by vshojo girls on twitter every time she makes a tweet, and it will suck because people will use it to shitpost when in reality she's just being nice.
