Nope, not gonna work... I could never go even from 3.6. to 3.7 without downtime cause of the settings change, see:
http://lists.gluster.org/pipermail/gluster-users.old/2015-September/023470.html Even when changing options in the older 3.6.x I had installed, my new 3.7.x server would not connect, so had to pretty much stop gluster in all servers, update to 3.7.x offline, then start gluster and all servers would see each other just fine.
