No, I am very much against your proposal. But I am very much for the stated 
goals behind your proposal.

Another way besides dual licensing which I agree is unworkable in this broad 
area. Besides, if I were willing to dual license my work under BY-SA and GPL, 
I would have no issue with letting my BY-SA work be converted to a GPL work.

No, it would not. It would suffer from the one of the same key weaknesses 
that 
concerns me copyleft wise with respect to photographs as does the current 
BY-SA license. At least from what I can see.

for possible losing the BY "protection"?

all the best,
