We experimented with H/E after immuno staining for a while.  It started when someone accidently counterstained with both Hematoxylin and Eosin.   The Pathologists liked it at first, and asked us to keep doing the mistaken H/E counterstain, but then decided the eosin made it hard to distinguish the DAB at times, and returned to the traditional hematoxylin counterstain.  The brown and orange contrast wasn't always good, but I am sure it depends on what you are trying to see.

We have done immuno's on sections stained H/e because the slides were all that were left to use.  Antigen Retrieval and H2O2 quenching (in our hands) removed much of the h/e stain.

Hi Jane,
How about doing the H & E after the immunostain? If your substrate 
is solvent resistant (like DAB) everything should work out fine! I'm 
sure others with more experience than me will also reply.
