I bought a very similar setup from boaters world a few years ago. It started as a 6 position panel just like that one. The main difference is it has circuit breakers instead of fuses.
I cut it down and mounted 4 of the switches in the change area of the upper console. Then I also mounted 3 other switches in the console.
It looks like this:
Underside
Installed
On the installed pic, you will notice i changed out the switches for smaller switches to control the lockers. I also added LEDs to know when the locker switches were on. I would say that after adding the LEDs, they are not worth the extra effort. The dash indicators work just fine to tell you when the switches are on. The wiring, FWIW.
Things I have noticed about the switches in this location. The upper 4th switch is a bit hard to get to, but you can get to it. I do not use these switches to get to anything I need quickly. I need to take my eyes off the road/trail to get to the upper switches. I can feel down there, but it is a stretch, I am taller as well.
I use the switches for my second battery relay, rock lights, work lights and the 4th switch is open. I also use the locker switches as well. I need to rewire the winch switch to work with the Warn winch. My old winch had the simple wiring that warn does not, have not had time to get it all set up and figure out the wires. I also have a wireless controller for it now, so it may never get done. The Key was used to lock out the winch, it controlled the ground to the winch so the key needed to be on for the winch to work.
I like the idea of switches overhead as well. I think in the Rockhard overhead center section would be a great place to put them. I have been thinking about how to use the wasted space on the panel over my head. Not sure if you have one of those MTDirk.
I also remote mounted relays to control higher amp items as well. I just built a panel and installed it behind the battery, when the battery was in a different place.
So, kinda a hijack, but hope this helps.

When I need more switches, that is where mine might go.
