Addictive Drums 2 and single audio drum track

We recently did a performance and the sound engineer combined the drum tracks (Kick, Snare, Toms, Overhead) into a single audio track.  I'd like to be able to use AD2 to attempt to separate the kit into their appropriate audio track using a combination of EQ and AD2. Is that even possible?  Unfortunately I can only work with what I have.  Any ideas would be greatly appreciated.  

You can try drum replacer but you'll never separate all the kit, you might have no problem extracting the kick and snare but the rest I doubt it. You need separate tracks. Toms might also work. 
 
If you have time on your hands you can duplicate the track manually note by note.
 
An example would be extract what you can with drum replacer, convert to midi so you can use AD for playback. Now using a keyboard controller or beter yet,  Digital drum pads, play the hi hat and whatnot to new midi tracks. 
 
Edit- ha ha I see Starise and me were typing at the same time and gave you the same answer--must be a good one :)

Does your version of SONAR include Melodyne?
Its audio-to-midi could offer some help? You could get an idea of it by dropping a snippet of the drum track on a MIDI track (?). I don't have the ARA Melodyne, but isn't that how it works?

I have a melodyne license it came with the platinum bundle.  And no.  Melodyne works really well on vocals or anything with a  real, recognizable pitch.  Precussion is a lot harder for it to decipher, because the waveform from a kit is just straight up noise.
 
Tell your sound engineer put some MIDI mics under those drums, or go back to college!  You can set 'em up for vibration or sound.  You'd at least have MIDI data to work with in that case.  They look like little flat sensors just slap em on with some strong adhesive and run their conduit appropriately to the hub. 
 
I don't like the latency if wireless but if your sound guy can tolerate it go for it.  They are also more pricy to go wireless.  But more convenient.  You're spending less money on duct tape and black spray paint and less of a chance your guitarist and/or vocalist will take a tumble.
 
The thing about live performance boils down to the acustics of the stage and all the ambient around the kit.  Makes anything working off audio triggers go crazy.  Vibration recommended.  It turns mastering into quite the challenge.  MIDI mics, and some samples right off your kit into XLN Addictive Drums 2 for the "Studio LP".

Thanks for all the input, I knew it wasn't going to be a quick endeavor.  I'll give it a go with duplicating tracks, EQing and using drum replacer.  I don't expect quality results.  It is what it is :(.

Addictive Trigger works well for separating Kick, snare and toms. I don't know of an effective way to break out the hats and cymbals. There is a fantastic video at Groove 3 on drum replacement that covers Addictive Trigger and Slate Digital Trigger.

You could also use Melodyne:
 
Copy the drum mix to a new track, Create region fx with melodyne and make sure the algorithm is set to percussion, select the snare drum hits in the first measure, choose select special in the edit dropdown menu, choose select same beats in all bars, choose select special again and choose invert note selection. That will select everything but the except the snare hits. If some hits are miss you can use the select tool and control+click to add them. Use the amplitude tool to lower the gain of everything selected. This will leave the snare track isolated, you could even delete everything but the snare on that track and/or export as midi to use in Addictive Drums. Select region effects and apply region effects.
Copy the drum mix and do the same for the kick track.
 
 
For toms you can split the drum mix at the tom hits and paste them into their own track(s). If you want the midi for them apply region effects ->Melodyne ->export as midi and adjust the midi in the piano roll view as needed.
 
You can create simulated overheads by using the above method and selecting kick, snare and tomsin the first step and lower the gain on them as needed.

You also may be able to dissect the parts drum replacer cannot get by inserting an EQ with high gain and Q (audio microscope) and finding a defined frequency that makes that piece stand out. Then run that signal through a gate till only the kit piece you are trying to recognize pokes through.

You may be able to drag/drop that onto a MIDI track or even use drum replacer to turn the blips into MIDI triggers.

Never tried that myself, but if problematic, manual MIDI insertion is a good fallback as mentioned above.

This video shows how to get midi from a stereo drum mix using Melodyne. He uses the stand alone version but it should work the same with the plugin version. https://www.youtube.com/watch?v=enYsjfCggvY
