As to the value of these combos each person will have to use their own judgement. I have the A9 camera and both MC11 and MBV. I have many of the Canon Great Whites (200/300/400/600). The adapted AF is moderate speed with some hunting in low light. Not really the best for fast action.
I have a Sony 400GM from the first batch. My first tests indicate the 400GM has extra IQ and AF speed when compared to my Great Whites (of various vintages). This is even true with the Sony 2.0 TC mounted. So if 800mm F5.6 is long enough for you the 400GM will so the job and it is, currently, the lightest extant.
Let us wait and see if Sony does in fact come out with this new APS-C camera with the features and capabilities of the A9, higher resolution, size of about the first generation A7/A7r cameras, and IBIS. If so, then maybe many of us can rely on that camera with our 100-400 GM lenses with the Sony 1.4X teleconverter that produces the equivalent to 840mm at f8. And if the camera would work well with the Sony teleconverter at f11 and be equivalent to 1200mm and offer excellent tracking and AF capabilities...That would be a very small and light package.
