So...what did you decide to do?
Not having ever used a torque wrench on an oil plug, I can't imagine draining all that expensive oil without trying it. I think you really have to crank pretty hard to strip these out (maybe someone else with a differing experience will chime in here). When I had my issue (last time I changed the oil), I just turned it the tiniest amount further and that did the trick.
If you
do drain the oil, I would think you could catch it in a clean container and re-use it.
