I had a live session a few years back where the kick drum mic was not working during the recording. I have the overheads track and snare track. The snare track has quite a bit of the kick in it. Is the Drum Replacer capable of detecting and separating the snare from the kick in a single track. I tried running it, but all I was able to extract was the snare. I've played with the threshold and timing but was but not able to extract and replace the kick.
 
Any suggestions? I am new to drum replacers.

It probably is if you filter it. You could either destructively filter out much of the high and mids to just let the kick through. There is a filter on the drumreplacer itself you can try as well. 

Filtering is crucial to obtaining the proper results.

I've had fairly good results doing exactly this. There was a bit of extra work involved though. Try setting the Filter knob somewhere around 40-60hz, and that should be mostly kick drum. However, there's more low end energy in snare hits than people often expect, so you'll likely end up with some snare hits detected too. So go through the track and click on the orange markers to turn off any stray snare hits.
 
It's a bit laborious, but it works really well. I've re-assembled a full kit fairly well from a single overhead mic by doing this for each drum in the kit.

The problem you'll have in your example is that the snare in the snare track will be significantly louder than the kick drum, meaning the threshold setting won't be very useful. You might well be better off using the overhead track.

try making a copy of the track, then using eq, hi-pass, lo-passs... to get mostly kick.

All good suggestions.  Another wrinkle for experimenting is to put a multiband compressor in there to do essentially dynamic eq.
 
Note too that while adjusting the filter you can hear it, so also use your ears to get the most of the low end kick out of it.  Also you can use the shift key while adjusting the filter to pick closer frequencies.

I would also use a clone ofone of the overheads. If the above suggestions don't get you there you might want to try Melodyne: click on one snare hit, and then select all the same notes in the drop down window. With all the snare notes highlighted, select the amplitude tool, and bring the snare hits down. Render and use the Drum Replacer and /or some of the above suggestions to isolate the kick hits. After you get only the kick hits you may want to drag the track to a midi track to trigger Addictive Drums or Session Drummer.
