As someone who has the Karve in brass already and is pleased with it (C plate is my favorite), I am intrigued by the potential stainless steel version. With the idea that cost may be a potential issue, I wonder if stainless steel top caps and plates will be available by themselves.
It might be a more affordable option (trial option) to get the more maintenance friendly stainless steel in the parts more likely to be a PITA to dry/clean on a regular basis in brass. Until I see the actual availability and pricing of stainless steel parts and the whole razor, consider me simply curious vs. excited. I am not opposed to a steel/brass Karve frankenrazor, but my skin won't care how it gets a great shave even if my eyes might.
Buy Brass black, put an antique look on it and voila, no need to worry about wiping it down every time.
