Combining two snare mics on one track

You should be able to combine them into one track by "bounce audio" which mixes whatever you select. The trick is getting just those two. So...
 
Mute everything  else, to "isolate" those two snare tracks. Then invert the phase of which ever one you want. Then bounce them to a new single track, checking the volume balance.
 
You should decide or try both, whether you want a mono or stereo track, as you bounce them.
 
If you save (ie don't delete) your original two snares, you can practice this several times and keep the best "outcome".
It's been a while but you might try soloing those two tracks, if muting everything is a PITA.

Ideally I want both snare audio files on one track in Sonar (8.5) so that all processing applies to both mics, rather than having to replicate all treatment exactly on two different tracks. However, one of the snare mics needs phase inverting, and phase invert applies in Sonar to all audio on a track, so both mic recordings would be inverted....

You can reverse phase independently for a stereo track's left and right channels with Channel Tools.
 

It is possible to effectively create a bus anywhere in SONAR see http://forum.cakewalk.com/FindPost/3050940

You don't really need to drag buses into a Track. Essentially, a track already is a bus; that's how Take Lanes work...the Lanes bus into the track. Put the two snare tracks in Take Lanes and whatever FX are in the track, including ProChannel, will process both tracks. (You may need to lower the lane levels via the track Gain control so when added together, they don't overload the inputs of the track FX.)
 
If one of the tracks needs to have its phase reversed (or for that matter, be processed independently with any effect), insert Channel Tools as a clip FX into the Take. The only significant limitation using Take Lanes compared to feeding individual tracks into a bus is you cannot automate Take Lanes separately. Any automation applied to the Track affects all Take Lanes. Then again, that may be exactly what you want if you don't want to copy multiple lanes of automation to various tracks.
 
However, as scook's link describes in more detail, you can also use conventional tracks with a bus, then send the bus output into a track via sidechaining and monitor only the sidechain input. The bus output appears just like a track, and is in the track view. Then you can hide the bus and even the source tracks if all you want is a single track that represents the output of source tracks going through a bus. It's not hard to set up, but you can always create a Track Template for this and load it as needed.

Here's another alternative. Bounce the two snare tracks to the left and right of a stereo clip. Put the stereo clip on a mono track and use the clip pan to adjust the balance between the two snare mics.
 

What a jump. From Sonar 5 to X3 represents 8 years of software evolution. Glad I don't have your learning curve in front of me.

You'll benefit from advances in Sonar support not only from the forum but with Cakewalk TV and the enormous amount of online videos and tutorials available today. Cakewalk has changed hands a few times in those 8 years but I think have finally found a stable home with Gibson and the X3 release has shown how well that is working.

...come to think of it, I don't think I've used Channel Tools, yet. I haven't really finished anything since upgrading to X3ePE (a lot to learn coming from 5.2)and that is about to change, so I am glad to know about it.

Channel Tools is exceptionally useful for a lot of different reasons. It really is a sort of "Swiss army knife" type of plug-in.

Thanks for all your replies. I hadn't realised/thought about Channel Tools at all, but I also take what you all say about keeping the snare mics separate until mixdown, which is what I may well do.
 
Thanks
