I had said currently, because it looks like you will be in luck with the 
next release (though it sounds like it needs a little config):

 From https://github.com/SchedMD/slurm/blob/master/RELEASE_NOTES:

  -- Allow nodes to be dynamically added and removed from the system. 
     MaxNodeCount to accomodate nodes created with dynamic node 
     (slurmd -Z<feature> --conf="") and scontrol.

All the best,
