Just getting an indication of how common this is.  The multilib stuff in 
[community] all takes the i686 package as the source and just moves the 
files to the new locations.  Is there some reason that you cannot use 
that approach.  Wouldn't all packages you are wanting to make a multilib 
package for have an i686 package floating about.  Also, with that 
approach you can actually make the package on the target architecture.
