Advice for making a UE4 project moddable/UGC?

Hi, I’ve been working on a UE4 project where I’m trying to remake a flash game. And turn their mods into modules that you mix and match to make Modpacks with them. I also want people to be able to make their own mods for the game. The problem is some of the mods modify the same classes such as the player character and I’m not sure how to achieve my goal.

Here are the potential ways I’ve found to mod a ue4 project. The first is to use ue4 DLC/patch system using plugins as shown in the Tom Looman guide. I like the look of this one, but I’m wondering if I can use two patches to modify the same function or class without them overriding each other.
The second is to soft code as many things as possible. Through I can see you being able to maybe replace class variables with a data table that you can load from memory, how would you soft code item branching? Like if my item has two different effects depending on Player stats.
The third is to use plugins like SimpleUGC, the problem I came across with this was that I can’t find it. I tried looking it up and clicking on links on a ue4 forum page, but no luck does anyone know what happened to it?
The fourth is to package the editor with my project which I don’t really understand this one at all.

What I’m looking for in a modding solution is something that allows for the modification of the same class by multiple mods without them overriding each other and allows adding of new characters, maps etc does anyone have advice?

UGC exists just fine, here’s a fork with ue5 support https://github.com/iveytron/UGCExample

The official links work, you just need to be logged into github and have access to the epic git (e.g. do the stuff you need to access the UE source code)
