Can DAG servers temporarily have different amounts of RAM

I have 4 Exchange 2010 virtual Citrix servers, 2 CAS and 2 DAG members.  I would like to take them offline one at a time and double their RAM.  No questions on the 2 front end CAS servers, I would just separately take them down one at a time.  But can I do the same thing with the DAG servers?  Plan A would be to move the active mailbox database copies to DAG server 2 and take DAG server 1 offline for the changes.  But when DAG server 1 is restarted and the DAG sees the two nodes once again DAG server 2 will have twice the amount of memory - is that going to be a problem when pushing the active mailbox copies over to DAG server 1 to finish the RAM upgrades?
In other words, will problems arise (quorum, witness server, etc,) if this is the way it is done?

No, you shouldn't have an issue. I did the same with my Exchange cluster in VMWare and there were no issues. I was able to move the DB's around and bring each node up without any issues.

With DAGs' you don't need to be running the same hardware on each DAG member.
