Geometry Modification Ingame

Hi all!

I’m looking to create a small puzzle game involving the modification of geometry, similar to what you can achieve with the Geometry Editing tools. Please see the attached images; I’d like the player to essentially be able to change Pic 1 into Pic 2. Does anyone know of any means to expose these controls (in a limited sense) during a game? Doing it in blueprints would be preferable but I understand if that’s unrealistic. Cheers!
