Basically I had idea for a Bugvisor kamen rider with the Okami HD gashat, but that evolved into a Bugvisor that isn't an actual bugvisor, but the literal history and world of Okam HD as a Bugvisor shaped tool, and the Okami HD gashat is a specialized gashat that acts as a key for the transformation. Think a bugvisor thats white with red detailing like all the Gods in the game, and the chainsaw part is a point of a paint brush, and the blast is slightly modded to look like a bow. The rider name would be, Kamen Rider Hitogami(literally, human-god), and would be a white and red Ex-aid rider, with wolf Ear traits and pure white goggles, along with the respective main weapon on the back(where the face from level 1 would be, so whatever weapon you have set as the main weapon) and the long coat skirt thing with beads trimming it(could be the divine beads or whatever weapon beads you choose and set as secondary weapon). You'd have a limited Pause, based on the freeze frame used with the Celestial Brush, which now is a Sword based on both a paint brush(ink on tip being transparent red plastic that lights up), and the sword you get from beating Orochi. Also an actual inventory with items from game.

Now the omnitrix one that came from this. Basically the same thing as the Bugvisor, but as a sealed amulet, thats turned into a watch, a literal sealed part of history and divinity, sealed in a wrist watch. The Brush Gods are sealed up and scattered, and the only way to unseal them is the Brush no Toki(brush of time, literally the watches name) Basically the basic abilitys and brush arts are channeled through the user and their finger tips, as well as a out of body drift that allows far away strokes(time is seemingly frozen during this, its the Freeze frame for the Brush ingame, but made as a separate ability). Each Brush God collected and or blessed the watch grants a form, with a more variety of abilitys, based on the god and animal, as well as traits based on abilitys, the monkey has three variants because of this. Some are directly the animal, some are humanoid morphs of them. With just Amaterasu inside, two forms, the Hitogami form, and the Inugami form. Regular human form is just the in-game limited Brush Arts, but the forms have more free range.

Hitogami can draw and stroke things into existence, basic things, like a brick wall, a sword, Basically kamen rider Ex-aid Mighty Creator VRX. And the few basic Celestial brush arts.

The inside of the Brush No Toki is basically a Celestial realm where the Brush Gods, as well as what other divinity and spirits enter live, along with the sealed off history thats Basically pruned from the timeline of the events of the game(s) of the franchise(kinda like the ridewatches from Zi-O).
