Can I get this kind of DOF out of the 35mm 1.8 DX???

Simple answer, you can't. To get the same image on DX as an image shot at 50mm and f/1.4 on FX, you'd need about a 35mm f/1 lens. The closest you'll find is the $1600 35mm f/1.4 which will still leave you with about a stop more DOF than the full frame image. This is assuming you are shooting wide open too. Certainly if you want shallow DOF, you don't want to be stopping down.

Aside from buying a new lens and/or camera, your best bet is to plan your shots such that your subject is as close as possible to the camera and the background is as far away as possible. Short of that, wrangle together $2000 and buy a used D700 and 50/1.4.
