From personal experience, I would suggest getting the beer up to 68 deg and pour it on top a yeast cake from your next batch (assuming it is a desired yeast strain and a compatible beer with a semi-low gravity). I have had stuck batches that have cleaned up well using this technique. You most likely will be over pitching, but it is way better than a viscous sweet mess!
If you have a stuck batch, pitching more yeast most likely won't work, especially if the alcohol level is already pretty high. Alcohol is actually toxic to yeast at higher concentration levels, so you want your yeast nice and healthy and well populated before exposing them to a toxic environment. Also, you want the yeast in an aneribic stage because at this point oxygen in your beer will not be good for the esters.
Good luck and cheers!
