Access to all variable from a BP in a Widget

Hi I want to know if it possible to create the details panel in UE4 but ingame in a Widget.

I want to have access to all my editable variable of an actor when I select it in game, so I can change the value of the variable of this actor in runtime.

I have differente actor so using a specifique structure is not possible, I need something more flexible.

Thx for your help
