Finding this discussed on a closed thread will require some research. And I hope it might not be necessary. Because as much as I like to discuss general practices of the wiki, they are also more likely to lead to an extended discussion. I promise to get back to you on this. But in the interests of making a decision easier to achieve, let me instead use a concrete analogy.
What we have is a character not even named in the book, based on what Borisashton said. So, clearly, no talk about some parallel universes or "Misterland" specifically is present in the stories, which are, after all, intended for 3-7-year-old children. In other words, a reader might recognise a familiar reference, but the characters in the story are completely oblivious to it being out-of-place. Right?
Well, meet the comic story Party Animals, where the Doctor(s) meet Bart Simpson, Captain Britain, the Hulk, the Silver Surfer, a Ferengi, John Steed and Emma Peel to name the most famous of the franchise crashers. Although I do not own this comic, I would assume that, as with many comic stories I've seen, there is zero attempt to explain where all these Marvels and Co appeared from or, indeed, to point out that they are out-of-place.
Despite all that, the story is valid, without causing the whole Marvel Cinematic Universe to sneak into the DWU, mind you. Sometimes the Hulk is just the Hulk.
While many of these character pages are not yet created, look at how Bart Simpson is treated with regard to the comic story Space Invaders!: "individual resembling Bart". If he's not named, we are not even sure it's him.
I'll try to find more examples if need be. But this is a better match than Assimilation.
