Moving Networks to new Region

Hello

We currently have a Hub-Spoke setup with the following..

1. Network Hub Vnet with 2 Palo Alto Firewalls Behind a Load Balancer and an Azure VPN Gate Way

2. Spoke Virtual Networks Peered with UDRs pointing to the Load Balancer IP.

I know you can move them regions but then would have to re-peer the networks. My question is can we just rebuild the same exact networks/ip ranges in the new region and then just migrate the existing virtual machines over? or is there a better way to tackle this?  it's not a lot of virtual machines we are just beginning our journey and discovered 1 region is cheaper than the other.
