I doubt I will ever make it in the near future, sorry. As I've replied to another person, I have a very busy schedule (I am in med school). I've been playing Minecraft and done stuff with commands for a few years, but I took a break from the game after 1.12 got released. In 1.13 they overhauled the way commands work and I've fallen behind. It would take me quite a while to get used to the new commands (for example I have no idea how the execute command works in the newest versions) and I simply don't have time for that. I have a couple of old maps stashed away that I am planning on releasing them after fixing them (but still for older version). As long as you don't have a problem with that, stay tuned for when I will upload them. If this is a problem for you, I am sorry for the disappointment, maybe I will port them for the latest version eventually, but almost certainly not in the near future, as mentioned previously.

I just downloaded a wendigo player skin and replaced the texture of the zombie with that one in the texture pack, since the player and the zombie share the same proportions.

Well, the reason i made it for 1.12 is because i am a pretty og player and i kinda fell behind in terms of how command blocks work nowadays; i am still used to the old commands and it would take me a while to relearn them.
