My battery wiring uses 99% of 5/16-inch Ring Terminal wiring. I have always followed the golden rule of no more than two ring terminals mounted to a 5/16-inch stud. One ring terminal placed on the lug in one direction and the second one flipped over for the second connection.. This keeps the Ring terminal lug ends from being bent when installed.
You are most definitely flirting with battery wiring failure doing something like this photo install from google

You will want to have a clean install arrangement of the wiring so that you can perform good observation of each connection and make sure they are not getting hot from corrosion or loose connections.
I like to use BLUE SEA HD Bus bar Terminal Studs are available from AMAZON. They also have covers for the POSITIVE terminals for protection from being shorted to ground.
Hopefully one can mount something like this off to the side somewhere so you can easily get to all of the battery connections with ease for inspections.
Just my thoughts...
