Their rates do vary... I've combined Twin Moon Bunny + Snow Giants over a hundred times and never succeeded.
Yeti 'n Pepe + Pharaoh Mummy is the easiest of the ones I've managed - since I kept track, I've had 3 Pharaoh Yetis and 11 C ranks, so ~21% success rate. Of course, that's combining A & A+ rank to make an A rank... which is relatively common compared with combining S + S to get S, or S + S to get SS.
