Exchange 2010 Hybrid - Server Roles Requirement

Hi,
 
We have an Exchange 2010 SP3 environment with 2 mailbox servers in DAG and 1 CAS/HUB server which is also configured for Hybrid.
 
Migration is completed and we want to remove the mailbox servers and keep only 1 server CAS/HUB for management as well as we want to keep email routing (both internet incoming and outgoing) via on premises exchange.
 
My question is, can I just go ahead and uninstall mailbox servers and we are left with 1 server with CAS and HUB roles and is also hybrid server? or I should install mailbox role as well on Hybrid server before remove mailbox servers/DAG?
 
I have read that for Hybrid management only CAS role is sufficient, I am keeping HUB because of email flow & connectors and thinking of also installing mailbox role because complete email routing is still via on premises, we do have some transport rules too. not 100% sure of it will impact anything.
 
Any advice will be appreciated.

      Hi NunoAriasSilva Thank you for response.

       

      What about the licensing if we migrate to Exchange 2016? As per below article, we are not entitled for Hybrid key if we have a valid Exchange 2010 or 2013 license.
