I think I understand what you're saying. If I'm understanding this correctly, I do this all the time with my midi tracks (which I have set to trigger intruments in Reason, similar to you and Superior). Here's what I do when I convert these files to waves:
1. Create a new track
2. Create a send to that track from the drum track, so that you are now getting the drum in this new track.
3. Right click the meter on the new track, and click on "Record: output => Record: output (mono)." When you record the cymbals and room mic, select the stereo option instead.
4. Record arm the track, and record.
5. Sit back, enjoy, and have some coffee or something
Hope this helps man.
