Probably not, but an interesting question.
Think of an Austin Champ in the same way you'd think of a Series 1, but more rare. It can be made capable, but the vehicle is more valuable kept original and the modification budget spent buying a coiler to start with. You'd end up with a better vehicle.
Champs are little delicate and spares are like rocking horse poop. IMV less capable than the LR Series vehicles, but they do have a certain cuteness to them.
Hope this helps
Cheers
