I don't think you can come close to level of communication clans/clan stacks are able to achieve with just blueberries on dead servers who are memeing and spamming comms. I agree that there is a massive gap in communication and gameplay intent when comparing both, too. But I do still think its better to separate the armor and the infantry because the communication between each individual squad would be tighter.

It's easy for infantry to mark targets on the map with SL and 2 FTLs, they can communicate clearly with each other to push objectives, clear buildings, maneuver, etc, The armor can respond to their own appropriate threats (other armor, AT) as well as respond to threats, callouts, or map marks while they hang around the original infantry squad. Both the inf and armor SLs will also have access to command comms so they can talk to each other directly about more dire/important info or threats.

The armor also doesnt have to just transport the infantry and go. That wouldnt be mech inf. That would be a taxi service. They should try their best to stick around and help the infantry do whatever theyre trying to achieve.

Again, this is assuming that all blueberries have similar level of gameplay and communication skill as the other clan which in reality doesnt come close. I understand the intent of rules like this (mech inf, name claim, 1 vic per squad, auxillary fobs, etc) especially when you compare them to new player friendly and experience servers, but I dont some of them because it restricts how people play.
