Questions about remixes

So, one of my favorite remixes of all time is E.T. (Dave Audé Club Mix) from Katy Perry and I was wondering if things like remixes ever float around in the form of track stems. Keep in mind that I'm not talking about the original track stems, I'm wondering about the fully remixed version with all of its pieces in a stem set.

to be fully honest mate its highly unlikely that the remixer would ever release thier stems, specially artists from chart and pop im not saying it never happens but is very rare... sorry can't help more
