Definitely.  This is what was done in Ubuntu for the multiarch conversion.

I don't think it's a bug at all.  Any amd64 package that required those
other lib32 packages for operation should have had a direct dependency on
them already, there's no reason that ia32-libs should continue to depend on
them for the benefit of third-party packages with buggy dependency
declarations.

That would be my recommendation.
