Cornering - Fixed vs Singlespeed

Won't work ! You either skid or stop there is no magic in the middle.

Skidding will work, like you say, but here we must apply the law of excluded middle.

Resist the pedal motion but continue forward traction lost - we call skidding.

Resist the pedal motion but slow (or stop) no traction lost - we call stopping or slowing.

i meant the second one, with out coming to a stop. just slowing your pedal circle to make it through the turn.
