Sounds silly, but there's just nothing like flying a 109 or 190 and having the same grip in your virtual cockpit as the real one sitting on/hanging from your desk. But it's hard to go back to one hat (with no push) and four buttons (not gonna count the Evo's base-buttons since this is a GF-request) once you got used to the plethora of buttons and hats on the MCG Pro.
So my question is: Are there any plans for a KG-12 Ultimate, perhaps made from metal? More importantly, with added functions? I could definitely see this thing gain an index-finger button/3-way hat on the top right side of the grip, an additional pinky button, a push for the hat-switch or perhaps even a second hat-switch. There are so many historical versions of this grip that one could probably cobble together some sort of Frankenstein-version based on real designs to get more functionality out of the grip without sacrificing too much of its historical flair/look. For example: There were LW grips that included a gun-mode selector switch on the left side - pretty sure those were used at least in the Hs-129 ground attacker.
If that isn't feasible without compromising the KG-12's look or handling... how about a more modern, post-WW2 Russian copy of the design or perhaps an F-4 Phantom-based grip? Kinda like the Virpil WarBRD grip which offers a bit more functions but still looks pretty vintage.

but as a business project I'm afraid it will be very difficult to return the investment. Sadly, it would take roughly the same time, and cost roughly the same money, to develop a modern/space age grip, and to make a new KG. Guess what is going to be more in demand.
