Hey,
Never tried that particular piece of reckless foolery :). However, I'd guess
that once the libraries were replaced with incompatible versions, the
installation scripts would start to fail, and then you'd be pretty badly
stuck.
Instead (but this requires a lot of disk space), perhaps install the 64-bit
versions of all current packages to a chroot, and then do a massive copy?
You'd have to be sure to get the important parts in one command on the copy,
otherwise your binaries might start being unusuable. (Or, install busybox and
use that to do things more carefully.)
The wiki has a couple other methods, if you don't have 15G to spare:

Hi all,
I installed 64-bit arch on a low memory laptop (1G) not thinking about the
higher memory requirement.
Now I wonder, whether I can approach to change it by changing the pacman.conf
entry
Architecture = auto
to
Architecture = i686
and reinstall all explicitly installed packages.
I feel like it should work.
Any "don't do that"s, "go for it"s, "I did it"s out there :o)).
