Splitting up the batteries and charging
I want to install a second battery dedicated to running the forced air furnace. I know there are going to be a lot of suggested alternatives like generators, catalytic heaters, rent a space with hook...

The plan is fine. However I agree with the others to just make one battery and use it as such. With all the manual switches it sounds like a pitn to manage and I speculate in time you will get bored and just leave it all connected as a group of four.
To truly isolate the second battery set I recommend a battery combiner such as a BIRD relay.
With the additional solar charging all as a group... you can always separate later if you really feel the need. What is missing in the analysis is the actual voltage during charging and discharge conditions. Also when you think the batteries are charged check them once with a hydrometer.
With all together you do gain some capacity due to the Peukert effect.
