I think the idea is very cool.
As someone who also has a number of wild ideas, I do have a suggestion though - one triggered by repechage's comment. Research the tensions that would be needed to build the wheels you want, and then also research the limitations of the rims you have in mind. If I went through all the effort that it sounds like this will involve, I'd be devastated if the rims began to fail while I'm truing the wheel, or possibly worse, one of the first times I went for a ride on them.
If you're able to do this, we will expect pictures.
