I'd use the two commands the other way around:
dpkg --get-selections [package-name-pattern...]
Get list of package selections, and write it to stdout. Without
a pattern, packages marked with state purge will not be shown.
dpkg --set-selections
Set package selections using file read from stdin. This file
should be in the format '<package> <state>', where state is one
of install, hold, deinstall or purge. Blank lines and comment
lines beginning with '#' are also permitted.
But yes, that seems the most sensible way to do it, though it seems OP
isn't really looking for the most sensible way:). I would assume that
with some dpkg abuse it should be possible to install a 64 kernel
(that also can run 32 userland), then maybe copy /lib and /usr/lib to
/lib32 and /usr/lib32 (and add those locations to /etc/ld.so.conf.d),
abuse dpkg some more that it starts installing 64 bit libraries and
executables, and ...
At some points in between you may well end up with a hosed system, but
well, if you don't mind that, it seems like an interesting route:).
