I'm in the middle of electrical upgrade and found interesting product from BlueSea: Automatic Charging Relay ML-ACR 7620 and 7622.
Is there any reason why either one should not be used as an "emergency combine" switch and ACR in one ?

Why would you want to do an "emergency combine?"
Emergency "combine" is not ideal description possibly redirect would be better
In scenarios where you have house or reserve/engine bank failures
For example:
House - failed
House: OFF
Reserve: ON
ACR: ON
Engine and panel are powered from reserve
Other than expense, no issues at all but you'd want the ML-ACR 7622 (https://shop.marinehowto.com/products/blue-sea-7622-ml-acr-500a-magnetic-latching-combining-relay) not the 7620. The 7620 does not have a manual override switch like the 7622..
The ML-ACR is an amazing product that can be used manually, remotely and in automatic mode. The only drawback is price. I use the ML-Battery switches on many boats as well as the ML-ACR. It's a wonderful product for getting more power to a windlass or thruster bank too.
After closer look I realized that it would not be possible to switch 7620 to ON with dead House bank (connected to always ON bus)
ML-ACR 7622 is the only valid option for 2-in-one setup posted above.
Price - not that far apart from any regular ACR + separate manual "combine switch"
