But if the readout was destructive but on-sensor (i.e. with minimal introduced read noise), it would be possible to duplicate the signal - one unamplified and one amplified to 800 ISO - to two separate off-sensor A/D converters (assuming Canon sticks with the off-sensor technology) and later combine them.
Yea, that's a good point.
It occurs to me though that, whilst the Exmor sensors are often spoken about as "ISO-less", you could probably still get some improvements by doing the same thing; thus pulling back a little further ahead. That said, if Canon could even just reduce the (large) current gap it would be very welcome.

Apparently the 5D4 will use similar dual-channel technology to increase DR too.
So, what's with the 5Ds? If the C300 Mk II, 5D4 and future Canon bodies have it, I can see the 5Ds having a very short life cycle, to be replaced next year by the 5Ds2 (which would be good for landscapes and architecture as well, not just studio work with controlled lighting).
It might, as mentioned in a recent post, explain some of the oddity that the new 5Ds is slumming it in what's essentially a 5D3 body and perhaps has been in gestation for a long time. Thus a 5D4 might be more like the 7DII in terms of extra controls, and have C300 II sensor technology. Given that I'd admit I don't really need huge MP for what I shoot these days, it'd be a very welcome camera for me. Kinda leaves the landscape shooters in the lurch again though.
