I definitely like the idea.
It hits the darker transformation/dehumanisation side of my kinks.
There is a lot of robot tf material out there, and in many different flavours and styles. Here is a sample of some resources I have on hand.

I'd also suggest checking out the "robotization" tag on Hypnohub, and searching for "robot" & "transformation" on exhentai. "Cyber F" is robo-tf artist with a lot of work available on exhentai, too.
