+1 for this problem.
we manage a club that has several husband and wife members that in the past have shared a common email address in our offline db. When we imported it into WA, we lost a significant portion of our member records due to doubled up email addresses. The hack you suggested does not seem certain enough for us to depend on, without an awkward membership email test to those members in this situation.
If usernames can be split from email addresses in the db, then we would have 95% of our problems solved. We can handle the invoicing through a bit of extra paperwork, so no big deal on that end.
