I think the title should be changed to "DK look alike fighter cab"...
I only want to mention one practical point you overlooked.
There is no way in the world you will be able to use that left joystick. Your hand will constantly hit the left side of the cab.
I know, because I own a "narrow" Mario Bros cab, and on that CP the joystick isn't even as close as yours is to the left and even so I keep hitting the sides. Yes I have very large hands, but yours is SO close to the edge....compare:
