I think I once had a similar error on SLES systems with one special "rhnlib" version that caused some dependency problems and thus removed some spacewalk stuff.

I remember. I think, it shouldn't be hard to modify that so you point it to the original "packages.gz", parse it and add the missing "Multi-Arch" header to the packages.gz created by spacewalk.

In fact, this could be used to add *all* missing original headers to the packages.gz file on spacewalk (when I think about it right now).
