Now we see through a glass, darkly...

Correct me if I'm wrong with your conversions, but do crop sensors affect a lens Aperture??? would the 100-500mm just turn into a 160-800mm 4.5-7.1?? etc
For exposure you don't need to apply the conversion factor.
For depth of field you do need to apply the conversion factor.
There's no such thing as "true equivalency" when comparing differently sized sensors.
