Today we have 1 parent domain XY and all our customers are sub-domains to this domain, i.e. XY/CUST1, XY/CUST2 and so forth. All our buy shipments are built in the parent domain XY and none of the sub domains can see these shipments. We are having issues with visibility when we have a customer, say XY/CUST1 who has 20 DC and wants 100% visibility to his orders, sell and buy shipments. The question is should we create a third domain level for this customer in the structure below and try to build this costumers buy shipments in his sub domain or should we create a new parent domain CUST1 on the same level as XY with 20 sub-domains so that the customer has 100% visibility to his orders, sell and buy shipments? See diagrams below, first diagram is our current structure, second diagram adding an third domain level, third diagram creating a new parent domain.

New structure with several parent domains for customers with several DC.

Does any one have any experience in setting up several parent domains and are there any implications in doing so for locations, carrier rates, Agents and so forth? Any thoughts on complications in the different setups would be highly appreciated.
Thanks,
