Trigger Blutility from Editor Widget?

Hi, I’m playing with the new Editor Utility Widgets and I’m wondering if it’s possible to open existing Blutilities from an Editor Widget?

I have some blutilities that have input variables for strings, materials, meshes etc and the blutility window nicely laid these out in slate UI - which Editor Widgets can’t seemingly do.

If this isn’t possible, are there any solid ways to make an equivalent UI in UMG?
