I'm sorry but that's something I don't understand at all, I guess, the tooling has been done you just use different methods and materials to get the different looks. Large manufacturers use this method for new dies can cost upwards of $100,000 or more so versatility is key. The button shapes would still be the same, they have to in order to fit the holes & locations, same w/the knob, the handle the same as well as the main facia. You wouldn't have to retool to do it, make a run of red buttons, a run of clear a run of glow in the dark whatever. I know what I'd want to do & make but I don't already have the equipment so it would be expensive for someonelse to come in & make new molds/tooling, when they already exist at Rio.
Yes if you were to change the whole layout & the look as to the shapes of the above that would be prohibitive.
