Possibly, but you do have to keep in mind that most rider shows have a prelim outline they work from. With later episodes having themes and concepts, but until it's fully sat down to write out and get the prep work going, it's usually anyone's guess. (Look at when we see filming for episodes in leaked photos, to then when the episodes air for example. With writing and prep work likely only done a few weeks before that if even that long.)

We will likely see them at various points, but when or how is up for debate. It's very rare that designs don't get used that are considered part of the show, but a lot of what we're told detail-wise is also hype to keep people guessing and keep surprises ready for their reveals.

But I'd personally assume that Kabuto armor at least will come up later when they do Hyper Kabuto. And others may get one off brief things like that. Looking at show themes and foreshadowing, at least Kiva, Kabuto, and Blade will get covered still. Hibiki is likely too. But how or when is definitely a question.

Ryuki seems likely too later. But some of those are potentially being saved for the upgraded forms later too. Like we've seen Ryuki armor, but not Ryuki Survive, and I'd be willing to bet Ryuki survive is one of those that will make it in the show because of the toy potential to the contract beasts itself as product that would move. Same as blade will likely make it in later, but the heavier emphasis of Blade will be on "King form", though it would be cool if Geiz got a Wild Chalice form too. Or depending on theme contrast, swap Zi-O and geiz in that regard. Really depends on what the toys have prepped for, what the show can work with from the data presets, and when they get to fully writing those episodes.

So I wouldn't expect them until later teens episodes or 20s. Also depends on when the turnover is too. Because typically a rider show does its normal build, does an initial climax turnover, to then back to normalcy but enhanced, then at least 2 more turnovers to shake up the show(but not limited to only 3 turnovers per season! Some have more, and it all depends on what the story itself calls for when). One of the turnovers is coming in the form of Decade though. So Kabuto likely won't be long after that. With Hibiki somewhere after that because of the "training" emphasis in Hibiki and the various other characters too. We also know potentially what two other future turnovers will be with Woz and Tsukuyomi.

So we have much more yet to see in character evolution and power ups. We're only at ep 12, and the really big story thrusts don't really kick in likely until the 30s. So that's a good 19 episodes of content we don't know about, with likely 2 of that as ghost, and then 2-3 of that as decade, which still leaves a good 14+ episodes unaccounted for before we reach the 30s. So bare minimum, a good 7 more rider shows will get 2 part episodes. Likely more, and that's not counting any that get doubled up or tripled up like Fourze/Faiz did.

And at one point, we will have 3 main riders that are cycling through armors too, not counting Woz and his specialty armor. So tributes to all 19 will make it in somehow. It's a celebratory show, it'd be remiss to not celebrate all 19+.
