Frexe,
An 11/16 hex wrench is .688 across the flats compared to .670 for 17mm. This may still grab even thought the 17 won't. If possible, use an impact wrench- this loosens stuck threads better than steady force on the wrench. Next best would be to whack the "L" wrench with a hammer while holding it into the plug.
To increase your odds, give the PB blaster a day or two to work. Reapply whenever you walk by the car.
The following all involve force/heat/tools/actions that can hurt people and break things. I've done most and lives but, as my wife often points out, God protects children and fools.
Gently heating the area with a heat gun or propane torch may help break it free. Allow expands faster than steel so the hole gets bigger relative to the plug.
If you take a file or Dremel and cut a notch in the plug's outer lip, you give a chisel or drift punch a better chance to work. Make sure it's in a spot where you can get a good, clean swing at the punch.
You could look for a bolt or component about the same level as the fill plug and isn't a blind hole. I didn't see what year you have but the 85.5 and up speedometer sensor looks like a good candidate. With this approach, you need to fill by volume then check the level since "correct" no longer applies.
A courageous person might drill a smaller hole through the plug then either use a rubber plug or retap for a smaller plug. Obviously metal chip management is crucial.
Hope this helps.

If all else fails, I don't think the risk would be very great to take Bill's suggestion and drill & tap a smaller hole through the plug. The tranny has a few magnets in there to catch steel wear filings (they look 'furry' when you open up the tranny). I'm not sure how well filling upsidedown would work unless you somehow plugged the vent. IIRC the vent cap can be removed so filling there might be a possibility...
