You could try the IMRs with the alkalines, but the combined voltage might be too high, and the thermistors might cut out. And don't horse it. That's 10.4 volts on a 6 volt motor. Use sparingly.

Do you have a couple dead AAs lying around. You can wrap them with aluminum foil to make them into simple conductors.

Bottom line, you can safely put 2 IMRs in a Stryfe with no issues. Three will trip the thermistor after a few seconds.
