How to use Argofet battery isolators when having 2 identical alternators to charge 3 non-identical batteries

At the moment in my boat, there are 2 identical alternators (max 65 A, max 14 V) and a
A) starter flooded battery
B) thruster flooded battery (that is not similar to the battery A)
C) house flooded deep cycle battery

I am thinking of purchasing Argofet battery isolators to divide the currents from the alternators to the batteries, but I am unsure if two Argofet battery isolators would interfere each other and cause an undesirable battery charging process. I am considering different arrangements:

Question 1
Is it technically (a) possible, (b) wise to use two Argofet 100 A - 2 battery isolators:

  • one for the first alternator to charge batteries A & C, and
  • another one for the second alternator to charge batteries B & C?

Question 2
Is it technically (a) possible, (b) wise to use two Argofet 100 A - 3 battery isolators:

  • one for the first alternator to charge all the batteries A, B and C, and
  • another one for the second alternator to charge all the same batteries A, B and C?

Question 3
As in the future, I may replace the two alternators with one bigger, let’s say 170 A alternator, I am thinking is it technically (a) possible, (b) wise, at the moment, to use

  • one bigger Argofet 200 A - 3 battery isolator for the first alternator to charge all the batteries A, B and C, and
  • one Argofet 100 A - 3 battery isolator for the second alternator to charge all the same batteries A, B and C?
