Can i use Slate UI and UE's graph/blueprint editor in a project made without UE?

I want to make a modding tool for my game that’s not made with UE.
I want to use Slate UI and the graph/blueprint editor from UE.
It would be free and i would give credit to Epic for Slate UI and the blueprint/graph editor.

  1. Can i use Slate UI in a project not using UE?

  2. Can i use the blueprint/graph editor in my project not using UE?

  3. If i can’t use the graph/blueprint editor in my project, how could i create something similar?

Under the UE4 EULA, you can only publicly distribute engine code, including engine tools, through the Unreal Marketplace or through Epic’s GitHub UnrealEngine network. (EULA 1(A)(b).) So, you wouldn’t be able to do this unless you distribute through those channels.
