Why no SKS magazine adaptor or bolt mod for ak47 magazines?

Hi Everyone.

I have been meaning to ask this question for a while now. It may have already been asked and answered, and I probably missed. If so, I apologize in advance.

Is there a reason why there are no SKS magazine adapter or bolt mod for making an SKS accept ak47 magazines?

The job has been done many times. Very successfully and in the case of the model M's, professionally
SKS receiver must be machined to accept ak47 magazine. Just not enough space without machining
As I understand it. 
It would be nice though if an adapter could be made. But that's not possible

The 'adapter' probably could be made relatively easy. The machining of the mag well and the rear latch point is the hard part. Why go to that much effort just to run a 10.00 mag? Use the standard mags that already fit and latch is the way we went after it. Except for the G9 which uses AR 15 mags.
