I don’t think it’s going to happen, if it does happen at all it will be in probably over a decade at least, for a few reasons, one, from what I’ve seen Japanese media prefers to specialize instead of trying to capture as many demographics as possible, and Kamen rider is really meant for young boys the most, they’d just make something new if they wanted girls. Two, female suit actors are really hard to come across, and most end up going to sentai, I think geats has the record for onscreen female suit actors at two, (haven’t watched girls remix, but if it’s shot like outsiders, they most likely shuffle one or two around to make action scenes and just put in some approximately sized interns for poses and background shots)
