Modeling the second autopilot panel would take a lot of time and I'd rather see the time spent on a new aircraft to be honest. This is something that addon developers would add because each aircraft costs as much as our whole sim.
And to correct the second guy: please don't assume things. Why shouldn't we add the shorter versions at some point? Shortening the fuselage and adding new repaints is not as big of a deal as building a new airplane from scratch.
