I completely agree that sometimes you have to find ways to make things work. And sometimes we get tunnel vision and forget to look for other solutions. So wise words.
But in this case, I think that is an extreme solution. As I understand it, the OP doesn't want to run custom brakes (required with a custom hub), and there is an easy to source 8" wheel that should work fine for him and has the look he wants. The only issue is the rear, and there are easy solutions there as long as he is willing to let go of his stock housing.
