Trying to move the marine type disconnect switch would not only be a chore, it would also drastically lengthen the cable run from your battery to the switch and then from the switch back to the fuse block. You would be introducing a significant amount of voltage drop in the process.
The better approach is to use a remote, solenoid operated disconnect system like the Intellitec BD-01. This system allows for the remote switch to be placed virtually anywhere you can run the small (18AWG) wires while the heavy duty solenoid is placed under the lounge between the batteries and the fuse block. And yes, you can run communication wires either to the display panel on curb side rear or all the way up to the front by the side door. I run these types of wires to both locations on a regular basis.
These type of devices are also available thru marine supply outlets from manufacturers like Blue Sea Systems and Marinco.
