Well - counting all edits, it is for sure possible. I mean, we maybe have:
SONG X - remix version.
Then there's also:
SONG X - Dub version
SONG X - extended remix version
SONG X - extended dub version
+ an instrumental of all those
etc etc.. there's so many remixes that are alike xD
If counting all, I think it is for sure possible
But you are for sure not counting remixes. ^^
