I see you and I did something similar! My RC Thomas isn't the flip-face version but it has the same battery-van body.
I just swapped the bottom part with a regular black truck frame+wheels+couplings and it worked just fine. I'll edit this post when I've taken a photo. Aside from the jarring visible screw on top, it's proven to be quite a useful van!
EDIT: Pics. Stickers are just there because I was bored :p
