On the face of it, No.

C'mon, How can two different OS images find the same binary when the storage
is not available in shared mode?

(NFS, one of the possible options in your case, is considered Shared
Storage, But then it could be a pain to configure to do what you want)

But it is just not worth it

Assuming both the nodes are identical in hardware, why not install all the
packages on say node 1. using yumand then copy the /var/cache/yum from that
node and do a yum install in node 2.

This may not be painful for small number of nodes but can can get unwieldy
if cluster nodes are large. In which case one should contemplete using
kickstart _before_ RHEL install. IOW, Plan properly


HTH
