Of course your first option is ideal, with the screen in landscape. Take more of your dash apart, particularlly the HVAC controls to see how they are operated. Some controls, even though they are mechanical, are actually cabled (kind of like a throttle cable or the brake cable on a bicycle). If they are cabled, it could be as easy as using longer cables to reach the noew location. If they are not cabled, then it's going to be extremely difficult to move. Also I think if you have to have the screen recressed that's actually a good thing, you will have much less glare.
