Of course not
you are clear about not be able to mix nodes with 4
and 5 versions, and because GFS needs the cluster
infrastructure to coordinate access to the FS then the
nodes with version 4 can _not_ coordinate with nodes
with version 5 so, if you soft force (you can mount
GFS in both clusters) that situation I guess you will
get a wonderfull FS corruption sometime (eventually)
depending of how intensive you do write operations
