For a), there's a couple of gender-swapped right and left throughs:.

"Convolution 2" by Merri Rudd
"House Husband's Reel" by Eric Conrad
"Jackson's Hornpipe" (traditional)
"Just Elegance" by Chris Page
"Pleasantly Surprised" by David Smukler
"Tuesday Child" by Brian Jones
"Women in Charge" by Melanie Axel-Lute
"Worth the Wait" by Tom Hinds

I don't know any in case b). It'd be awful confusing, kind of like a
petronella turn to the left, as there's nothing in the set-up of the
move  to force a clockwise courtesy turn.

In category c):
(often pairs of proper right and left throughs with different people
one the left/right at different times)

"Crestwood Reel" (traditional)
"The Double Plow" by Al Olson
"Double Plow #4" by Al Olson
"Elegance and Simplicity" (traditional)
"New Mountain Contra" by Al Olson
"On Alternate Sides" by Al Olson
"Path to the Past" by Chris Page
"Up to My Ears in Right and Left" by Larry Jennings
