Hi David, I'm not a big fan of the Workgroup Edition since it's impossible to ever add a 6th user.
However, you could use a trial license of CRM 2011 Enterprise Edition to complete the upgrade. CRM 2011 has a new feature which allows you to delete a user (not just deactive a user, which was a limitation of CRM 3.0 and 4.0, as you've stated). Then redeploy
the CRM 2011 Enterprise Edition system into your production CRM 2011 Workgroup Edition system.
Hope this helps.
