hot click area will require gauges to perform that action. While it is easy to program a simple xml gauge to do the job, it is even easier to just use the simicons included in MSFS to swap views. The IFR and VFR views are great for building a 3/4 panel and a 1/3 panel. The engine stack can be used for the FEs position and there are multiple options in the FSX simicons for different views. Using a program like FSPS makes it all WYSIWYG.

The problem I ran into with building a 727 panel is that CS did not build any 2D switches (with the exception of a very few). Thus 90% of what you need to interact with the airplane will need to come from other sources.
