Just realized that we don't have a CHUG versions of Pipes & Outback. Practically all the other minibots have had a new version done. Outback can be made from the Henkei Brawn version. Though I have heard some ideas of the Swerve/Gears mold can be used. Pipes is an easy one, another version of the Optimus mold with a new head.
I know that RtS Fallback can be repurposed as Outback, it just doesn't fit well with the rest of my CHUG's.
Anyway, my 2 cents :D
