2001 Marlin - I don't like the setup for my electronics. When I'm underway, the door falls down, and the visibility is not great with the device set back in the box.

I've already taken the doors off, plan to cut a piece of plastic and mount the GPS/Fish finder and VHF as you see in the second pic albeit a bit less seamless. Any suggestions or potential issues that I should incorporate into the plan?
