2d sidescroller to 3d

Hello, this is gonna sound a little weird I think. I made my project originally as a 2d sidescroller and quickly at the start I chose to change my game to a 3d sidescroller so I changed the camera view in the 2d character to preservative and went on with the creation of the world. Now I finished making and animating my 3d character model and i want to replace my 2d one, however I added a considerable amount of variables and blueprints to my 2d sidescroller character and I don’t want to see that gone, so is there a way i can quickly replace the 2d sprite in my character blueprint with a 3d one and continue with the same blueprint rather than starting over, and if there is a way what should I put in place of the update animation and the set flipbook nodes I’m using.

Thank you!
