ISTR the 9280 needs a 20a breaker (vs 15a) protected circuit with 12 vs 14 wire for input. So as a replacement for a 55 amp converter, more mods are needed on the input side.
You can keep both converters as another option--could come in handy at times.
Output side wiring depends on distance to battery bank. To get 80 amps (most seem to do a bit under that with PD design) you will want at least shorter #4 AWG. A forum member, Fisherguy, reported on his 9280 installation a couple years ago and got decent charging with 7 ft of #4 ISTR
Your choice how to do the battery bank to keep wiring to a minimum. You can discharge and recharge the two 6s and the two 12s as a bank of four together while camping, but to recharge them fully at home, you will need to separate the 6s and 12s for the last bit of charging to 100% for their different charging specs. So arrange for an easy disconnect in their connecting links.
You can exploit the twin DC output terminals a number of ways. One thing is you can mount the 80 amper next to your inverter, link them with short wire, and run one set of fat wire from them to the battery bank. (vs two sets of fat wire to the battery bank)
