Ask HN: Possible to turn a Google Apps account into a regular Google account?

I've looked all over the past week trying to figure out if there were a viable way to turn my Google Apps admin account which is just me on the domain into a regular ol' Google account without Gmail. The search has left me more confused than anything.

I remember being able to create a Google account with an email at another domain that didn't have Gmail enabled, I'd like to turn my sole account on my Google Apps setup into one of those now that I've transitioned all my email over to a separate provider, but I'd like to maintain access to Google Docs that have been shared with me.

Tips? Advice?
