Is that not being negative? If you have a wheel missing, fixing it seems to be an option, just so you can move the damned thing round the shed, or showground. Given a collection such as has been gathered here I would be inclined to assemble, or spend out on, one set of really good wheels and then move them between the cars I might want to drive on the road. A bit like having three racing cars and one £25k tuned engine. It resolves cost control, competitive edge - in this case insurance requirements, and you still have the satisfaction of proving that you can do a rather tricky repair.
