Actually, I don't think the names work like that. While we have few data points to go off off, what it looks like to me based on the little we do have is that the Best Matches have their own unique naming conventions, but otherwise, the forms simply use the names of their Full Bottles. This is based off the fact that eight of the 10 Best Matches change the names in at least one way (most very arbitrarily), and that the Remix Rider listing refers to the Harinezumi Tank and Rabbit Soujiki forms as...well, Harinezumi Tank and Rabbit Soujiki. The first picture we got of Rabbit Soujiki also has the word "Soujiki" spelled out in the background.

If I'm not wrong, the names should go more like this:


Of course, I could be wrong, since we've only seen 3 non-Best Match forms, and one of them wouldn't be any different one way or the other. But it's my hypothesis for now.
