I don't understand why you worry so much about resolution of older prime lens.
For D7000, 16MP 23.6x15.6mm2 size, it would be around 208pixel/mm.
For D800, 36MP 36x24mm2 size, it would be around 204pixel/mm.
If you dont have problem using 85f1.4D or 50f1.4D on D7000, why should you have problem using on D800?
You have answered your own question... 85 f1.4D & 50 f1.4D cannot even resolve properly for a 12 mpx crop camera in my standards.
On the D300S it is compulsory for me to stop down to f2 for the case of the 85 f1.4D. This is not autofocus issue. Depth is plenty at crop factor shooting distances.
For the case of 50 f1.4D it is more of the horrendous CA for most copies (some of the made in japan ones seem to perform better). There is still sharpness within the heavy CA.
