Remote move to Office 365 - multiple tenants, one exchange

Our situation:

1 Active Directory, multiple companies
All federated to separate Office 365 tenants, but federated to same on premise domain and exchange.

We need to move the mailboxes.

Will remote move work in that scenario? Or is the limitation that we can only connect to one tenant at a time for remote mailbox moves and then sever the connection afterwards?

Or is there a powershell command to create the mailbox in the cloud and then use third party migration tools? :)

While you can have multiple dirsync/aadsync/aadconnect instances syncing the same AD forest to separate O365 tenants, Hybrid is possible with one tenant only.

The cmdlet is New-RemoteMailbox :)

When you've setup hybrid and done your remote mailbox move... can you easily break hybrid afterwards once everything is across? :)
