Uh why not use the actual Lizard Man King and Orc Stat blocks?
Two different reasons.
I didn't use the Lizard Man King because I wanted to use a DRAGON and all the special abilities associated with it (breath weapon, lair effects, etc) without using a dragon. I wanted to use the mechanics of the dragons without the "fluff" associated with it.
That's also why I made a dinosaur a cave troll. I wanted to use the STOMP ability.
I didn't use the Orcs because I wanted some variety. It was a raiding party and it had 4 or 5 different low level creatures. I didn't want them to add be the same so I just reskinned the other monsters as an orc. Some of the "orcs" had AC 15 some had 12, some used man catchers, some had axes, some had 20 hit points, some has 11, some had the ability to disarm, some didn't. Variety is the spice of combat

I also ran a combat with two "ice elementals". One was a water elemental and the other was an air elemental. Two similar monsters with slightly different stats and abilities.
