Yasuko Kobayashi is also very unlikely because she has actively avoided writing crossovers for Rider. She used to write the spring movies when they were Den-O focused, but as soon as the crossovers became bigger (Episode Yellow, Let's go Kamen Riders), she dropped out. She didn't write anything for Movie Wars Core, and just the OOO part in Megamax. Climax Deka and the original Chou Den-O movie had minimal presence of the guest Riders. She did write four Decade episodes as a secondary writer, but those four episodes were the ones focused on Den-O and Shinkenger, her own series.

It seems very unlikely she'd write a crossover show.

Regarding "Blood" though, we do have the oddity of several Build characters in the gimmick action figure toyline for Zi-O (Build, Cross-Z, Build Cross-Z, Evol), so that could indicate them all appearing in several episodes.
