That's pretty much exactly what I've done for the last 8 years or so,
and it works really well.
Our current incarnation is to netboot a minimal RHEL image on diskless
nodes (managed via xCAT) and then all the applications are in
/usr/local including various Perl, Python and R versions with their
associated module hell. At the moment we've got about 638 different
modules across 3 different architectures.
The main reason for RHEL on compute nodes is to keep hardware support
people happy, most vendors take the Blue Brothers approach to Linux
("we support both kinds of Linux, RHEL *and* SLES").
We only have a handful of commercial applications, but we've never had
an issue with what they support in terms of OS.
All the best,
