Default Battery switches, combiners, and trolling motor

Guys, I am looking for some feedback to make sure my idea will work as expected.

Working on a few upgrades for my new to me boat. It is powered by twin outboards. Currently I have 4 batteries, 2 per side. Each side has a single off/1/2/all switch. I am adding a 36volt trolling motor, so while I am at it, I might as well get the system right. Most of my runs are 30 to 60 miles one way. A typical day consists of running out, 2 to 4 hrs of trolling, 2 to 4 hours of drifting and bottom fishing or jigging. I mostly drift due to not wanting to drop the anchor, thus the trolling motor. The boat is kept mostly in dry parking with no power source. I also have a wet slip with power which is typically used when I will fish 2 or 3 days in a row. My house loads are not considerable. No huge stereo, ac or anything like that.

My plan is to remove the current battery switches and replace with Marinco/BEP pro installer dual bank switches. I will parallel the two house batteries and install a combiner 100 to each start battery to the house bank. I will then have a trollbridge 36 connected to the house bank and trolling motor batteries. I will also add a 3 bank charger connected to the two start batteries and the house bank.

If I understand correctly, this should separate the house from the starting, unless I go to the combine position. The combiners should charge the house bank from either or both engines. The trolling motor batteries.
should also be charged, once the house bank is full whether Im on shore power or engine alternators.

Sound ok?
