Well, that's not a setup I'd want for myself (though I do see the
advantages you're mentioning), but for people who want to do that, it's
probably not something that the distro needs to specifically package.
There's nothing at all really stopping you from putting a 64-bit kernel
on your 32-bit install, and actually at work, I have even done that on
some of the nodes of one of our research computational clusters, where
almost everything is 32-bit, but we still want the extra memory. You
just drop your kernel on.

The only package I've seen that seems to absolutely hate that setup is
iptables, since it comes with userland commands that integrate very
tightly with what's in the kernel, and it doesn't seem to work to have
the binaries be 32-bit and the kernel be 64. You'd probably have to get
a 64-bit iptables package to make that work.
