Yes you can, without any special routing either:
Open up SI Drums with both a midi and audio track.
Arm the audio track, mouse to your heart's content.
Drag the finished audio file to the midi track. Wait for Sonar to do its thing.
Your audio is now midi. You can move the notes around in Piano Roll.
Caution: You may have to relocate the resultant midi drums to different notes on the piano roll. I recorded the snare and Sonar put them on A5 instead of D3. On A5 you will hear nothing. On D3 I heard the snare.
