REQUESTS KARMA INVOLVED

For the Wall, use a Heidenreich head maybe. If you want him to be in "ring gear" just use a body of someone in a dress shirt/pants. Pop open the body, and switch the arms to plain ones. Slap any spare sunglasses you may have on him.

For Bull Buchanon, a Tyson Tomko head would likely be your best bet. Slice off the goatee, and sand away he paint. I don't know what look of his you are going for though. Is it the one of him as Bossmans sidekick? Cena's sidekick? Or his run as a casual grappler?

Without molding ability, the bossman option may be out of reach. As cena's sidekick, just use Matt Hardy legs, and a heavyweight torso. For the late run as a casual grappler, just use Haas legs, and heavyweight torso.

Finlay is a tad tough. You should definitely use a Jay Strongbow body, and just add paint to the legs to make it seem like shorts. As for heads, I really don't know. Heidenreich could work, but if you use it for Wall as well, it'd be odd. Maybe someone else can help with this.
