I just got done looking at this same issue. I instlled the license file on the server that will be the DR license master, then changed it to a slave pointing to the license master. No problem. I then went back and changed it (using gthe GUI, so I can write DR failover instructions for someopne who is not a Splunk expert) to a standalone, again - no problem, license was still there. The remaining DR task would be to point the rest of the servers in our environment to the backup license server.
So, the short answer: Yes, I thnk so. Test it in your environment, I haven't set up a deployment server yet but it seems to work fine and there are no error messages anywhere.
