AFAIR they always talk

yes, I read the doc yesterday. seem very interesting.
The most work could be to replace pmxcs by consul kv store. I have seen some

Sure, such things can extend the node count of a single cluster. But I am not
100% sure
if that solves all problems

Exactly. Corosync is much better/faster and can repl

From what I read, the use 1 quorum in each DC.
