Well, I have my SBSE box downgraded to a workgroup and other than removing a couple of roles and altering a DNS entry, it did not pose any issues, so far. I probably broke the EULA but I'm testing so come and lock me up. 
I did take a snapshot of the box before attempting this so going back is no issue. The next thing to do is join a client and see what happens..
Yes, I've done the same -- it's fairly easy actually --:
Remove the Role for Active Directory Certificate Services
Reboot
Go into Command Prompt as Administrator and run dcpromo
Go thru the Wizzard -- since this was a fresh install in VM -- I didn't worry about the warnings (OK, maybe I did) and worked my way thru the wizzard
It'll ask for a new PW for the Administrator Account
Reboot
There you are in the wonderful world of workgroups
I can now see SBS2011e and SBS2011e can see all of my other PC's & Servers
I took a couple of snapshots before doing this so I can go back
I'm going to have to create a VM of a test Client to try Joining to SBS2011e now.
