Is it legal to release a modding kit editor that includes Marketplace content?

If I release an editor for my modding my game, via epic launcher ofcourse, would it be legally permissible to include marketplace asset used in the game to be shipped with the modding kit/Editor ?

Since they are uasset files it would still be possible to extract them and other things you can do with the editor already.

Is there any other ways around it say by removing the export functionality of the editor ? Although the asset would still be useable as uasset in other ue4 projects by simply copy pasting.

I wonder what’s epic’s stance regarding that is
