Note that I am not saying that all Kevin's unpublished submissions are so similar that they should be in the same collection. But Centaur Spiel and Janus Spiel only differ from Accelerated Courier Spiel in that there are two C or two A instead of A + C, and that seems worth hardly more than a footnote.
Kirin, Waffle and Lancer Spiel are a bit less similar, because these start the pieces in different locations. But they are still very similar in character because of the presence of Guard and Centaur. Perhaps more than a footnote, but a collection that treats them on equal footing (like CwDA) would be a better solution, I think.
Horse-Wazir Spiel is sufficiently different in character to warrant an article of its own, I think. Unlike the others, which add super-pieces, it only adds minors.
