The Snake Men are definitely cool! I have always liked them. MYP made them seriously dangerous but I prefer the origin story as told in the mini-comics, where Tung Lashor and Rattlor were indentured into service for Hordak over the millennia of King Hiss' interdimensional imprisonment.
Having recently seen the MYP series, I definitely would love to see variants/repaints of Snake Teela, Man-At-Arms and most especially Mekaneck released in MOTUC. Snake Mekaneck would be the only excuse to break my no-plug-in neck extensions rule!
I'm so disappointed that King Hiss' MOTUC snake body is so pathetic and underwhelming.
