Azure Arc Private link scope regions

Hi, I am creating a following architecture:

 

 

 

I am new to this so please forgive me. But what this picture says is that i have two ExpressRoute connection from my on-premise AD to the gateway in West Europe Region and North Europe Region. I am trying to create a fully private connection to the Azure Arc. I succeded by adding one Azure Arc Private Link scope per region and private endpoint. But when i deploy azure Arc using the script I can explicitly choose a region for this machine to belong. Since in Azure you pay per data transfer and you pay extra per trans-region transfer, will this create any extra costs if i deploy all my machines as North europe machines, given that data will be flowing through AAPLS from West Europe. And what about Azure monitor Agent? If I use the same architecture but using Azure Monitor Private Link scope:

 

 

 

This is my architecture now, because machines going through West Europe ExpressRoute had been deployed into West Europe Region using Azure Arc. But if they were deployed inside North Europe region using the logic above, would I pay extra for trans-region transfer? I am having a trouble with this region architecture.

But even if i deploy my machines in azure Arc in North Europe, the physical connection via ExpressRoute is still attached to West Europe so if I deploy AMA using Data Collection rule the logs will physically flow through west europe anyway. The only difference will be a logical belonging of machines going through west europe ExpressRoute to North Europe region. Maybe its absolutely impossible to do that and if i have azure arc private link scope in West europe i cannot assign antoher region to the arc enabled machine.

Can you please help me with that?
