If we are talking fictional cameras (1D-X) id go:
50mm Cinema Prime
24-70mm f2.8 L
If the Cinema camera does stills well enough that would be a tempting offer (assuming the equipment is bought and paid for, of course).
I do a lot of birding photography so the full frame camera restriction could be harmful. On the other hand, I could still just throw a TC on (I'll assume that fits in for flashes and tripods, which I generally don't use).
My setup would probably also be something like this:
85mm f/1.2L II
Sigma 120-300mm f/2.8 OS (still nothing comparable from Canon - a 400mm f/2.8 zoom would be better, of course, but also considerably heavier...actually, why not a 300mm f/2? Nikon did it before, albeit in prime format.)
I would sorely miss my 135mm f/2L and especially my tilt-shift lenses, though...so perhaps actually I would be better served trading the 85mm f/1.2L II for the TS-E 90mm f/2.8.
Ultimately, this is a no starter for me because I need different lenses for different subjects - it's not just optional. Taking a picture of a building from the street with a 85mm lens is not going to work well - it needs a wide angle (and it had better be a shift lens, as well).
