You sound like you REALLY know what you are talking about ... or a really nice actor...

Or maybe both!!! hahaha...

It can always be done. I only see that you have a panel for an AC voltage system, between 240 and 120.

That obviously you can't drive it directly with an arduino but the control can be done with a coupling circuit using TRIACS. The buttons and switches can be connected to the discrete inputs of the arduino and the rest would be programming a control logic in the Arduino, as I said before.
