Well, right.  There's no way to automatically map all 32-bit packages
to their 64-bit counterparts, particularly because there isn't always a
64-bit package to map to.  What I was suggesting was a method you could
use to make a first pass at the 64-bit packages that you want to download.
It won't be perfect but it would be a quicker alternative to doing this
all manually.  But if 64-bit packages are what you're looking for, you
definitely have to go through some process for this once.  After that,
you can employ the same technique to replicate your 64-bit installation
elsewhere.
