Forget it, don't even try. You might succeed, but it will not be worth the 
effort. You will complete the following steps in about half the time:

1. Back up /etc and anything else you want to keep
2. Reinstall
3. Set CHOST to something suitable
4. emerge -e world
5. Restore stuff from step #1

It's an interesting exercise to try and do the migration, people who like 
puzzles enjoy it. If your goal is to have a 64 bit system using the route of 
least pain, best to follow the path with lots of consensus around here - the 
one above.
