I suspect the benefits may not be as great as having double the 
effective wire x-sectional area would suggest since proximity effect 
would be working against you (as it does with any closewind. I could 
have done that with my 10" coil (the one which I described my space-
winding technique for) but in the end, I didn't, and I wasn't 
disappointed with the result.

I'm sure it's been done. I think it would just cost more and be 
heavier. Someone who's done it and seen before and after results may 
disagree with that opinion though.
