A few Sk models have been ported to GMod.

A guy by the name of system76 made ragdolls and player models of the starter armors (+ the Metal Sonic suit) along with models of most of the swords.

The swords sadly lack their shiny particle effects, there's no hamma, Obsidian looks utterly weird and the closest thing to the good ole' Acheron is a red-colored Nightblade, but there's the ban stick(kinda redundant, since it's Gmod), the cool looking early-game swords and even Groot's pan(obligatory stout shako for 2ce), while the knights themselves work well, you can change their eyes, helmet/armor combination(including no helmet, boy did that look weird) and armor color scheme(dusky, military, etc) via the easy bodygroup tool, and they come equipped with a special tool for changing their personal color(that being whichever color you want, you get the whole MS Paint-esque color pallete). Haven't checked the comment section so I have no confirmation on whether he/she's going to continue with more weps, armors and mooks or not.
Might as well use that Summer sale to get Gmod and attempt animating, too bad I'll probably be away from my PC for the rest of the summer to try anything myself.

Gmod, or as it's officially known, Garry's Mod, is a Source-based(the engine made by Valve for their millenial games like Half-Life 2, Portal, TF2) sandbox where you basically mess about with the engine's physics using various tools and models, such as a vast collection of props and ragdolls, anti-gravity devices, thrusters, or the Physics Gun, which allows you to drag objects around and freeze them in place. Some creative people got the idea to use the game's model posing tools combined with screenshots to essentially make half stop-motion half puppet animations.

(Warning: the person responsible for the guide is a bit of a foul mouth, also ignore the Orange Box bit, Gmod works by itself and you can get a bunch more props by downloding the free TF2)
Yes, it's a little weird going in such a engine-mechanics-savyy game from a casual MMO, but I think it's possible.

...I want to check Gmod out but my brain is peeling from trying to understand it. YouTube, here I come...
Also, do you have to code things to get them to work? Because I know absolutely nothing about coding, what tiny bit I did know from Unity got forgotten.
(Ohhhhh, that's what TF2 is...ha.)

This looks to be a start of great things to come. But will the adventures end on good terms?

You have to subscribe to the addon on the workshop(the link in the first post), it will automaticallly add everything to the game. They should show up in the spawn menu(Q key by default) in the addons folder.

Thanks to OP now i can make videos explaining how Silver-Core is actually a gremlin terrorist!
RIP Silver
But seriously,
This can actually be useful.

At long last, my dream since 2012 has finally come true. God is real.
And if you want your own stuff ported, see this thread:

Deided I would try something with it.

Maybe this should be moved to the Treasure Vault subforum once this thread begins picking up more screenshot posts.
I'm confused. I looked at the link and I can't tell what this actually is. Is it a character creator, a system to install, a way to animate or what? I feel like I might've nailed it down somewhere in there, or that it's something you insert into Photoshop type software. but I have no idea.
I'm just a clueless person who feels like she's looking at another language....
