I'm not sure about Hiroki Iijima.

Both are busy with a musical named Shirotora (with Ryuga from GARO as well), so not sure if they are available if the musical is on tour.

Decade's Masahiro Inoue is busy with his own GARO Spin-off, starting October on TV (and unlike Kamen Rider, GARO asks a lot from their protag on a physical level for fighting scenes as they rarely have body doubles for their impressive choreographies).
So don't know if he can be available enough to shoot a KR movie and a GARO show at the same time.
I would expect a short appearance in the show, because anniversary + the upgrade thing, but I would not expect him to that present.
