Sanity Check Needed on Short-Term House Bank Configuration

I need to set up a higher capacity house bank for several months, and have at my disposal the following 12V batteries:

2x 110 AH AGM (same type/age)
2x 110 AH Flooded Deep Cycle (same type/age)
1x 95 AH Flooded Deep Cycle

While I know it's common opinion that it's most optimal having all batteries in a given house bank be of the same type and age, I'm assuming that having all of the above in the same bank will be workable for a few months without major problems.

The single 95 AH battery will get worked harder, depleted further each charge cycle, etc. but I'm considering that particular one "disposable". If it lasts 3-5 months, I will be happy to have the little bit of extra capacity in the bank. The two types of 110 AH batteries should get along fine together as they have nearly identical specs as far as charge rates, voltage, etc.

I will be charging the bank with a Sterling 30A smart charger and recharging when the bank gets down to 80%.

So.... what am I missing?
