I think if your C2C is 125 mm then the Turbomatic is plenty wide, even though the flat area of your ischial tuberosities appears to be very long. I am thinking that if you try to support the entire O2O width, then you'll never find a saddle with a nose or a transition area narrow enough to accommodate a 65 mm I2I. And since the problems you're having now are related to the transition area being too wide, I'd give it a try if you can find one that you don't have to commit to. You might just find yourself hanging off hard turns as though you were on a motorcycle. Except off the "wrong" side. 
I still recommend making a tracing of your sitbone indentations, that you can then lay over any saddle without even putting it on a bike. You can't get a definite "yes" from a saddle that way, but you sure can identify a lot of "no"s, not only by width but by shape.
