ZI-O Zukan has these pics of the Kasshine. Saw these around /m/ and a nice discussion around it.

The one in the middle is obviously Storious/Solomon's suit. There are 4 others around him that look similar, but use different armor.

Storious was with the four sages. It's entirely possible we might see all the kasshine suits repurposed.

While I'm not a fan of these being a "final enemy thing" for Saber, I'll at least hope they won't look too bad. Storious' rider suit looks fine enough besides it being, well, a kitbash.
