I agree with many aspects of your proposal. I have done many test with 
using background-size and background-position with radial-gradient. I 
also agree with some of the comments that Brian has added (ei. repeating 
halves of radial-gradient).

Others concerns I have is that the way the spec stands now, using both 
linear-gradient and radial-gradient together are not easy.

When magic corners work, this technique will only work with boxes of the 
same height and width.

I have many offline test with gradients but many need to be deleted. I 
will drop my desire for premultiplied gradients (yes i said it) so I can 
contribute to something good.
