What we really need, is what the x86/x64 side calls multi-library. The ability to run either 32 or 64 bit binaries. Any package loaded, that supplies libraries, would have both. Each non-library package could determine what would be best based on need. Like LibreOffice & Gimp would probably work better as 64 bit binaries. On the other hand, terminal emulators and Vim would probably work just fine as 32 bit binaries.
