Freestyle depth of field I am using Freestyle on a Cycles scene with some depth of field. The Freestyle doesn't get affected by the depth of field, and so pops out too much on objects that aren't in focus. I am looking for any sort of trick or method to get some blur on that FS without also blurring it on the focus.

I could switch to doing fake DoF on the whole scene in post processing, but are there any other options?
Freestyle is applied after the actual render, so the short answer is: no, you have to work with post processing (maybe filtering the freestyle edges with a Kirsch filter and apply the blur only to that portion of the image). 

But, you might be able to fake something using the "Distance from camera" modifiers in freestyle. This modifier can be applied to color, alpha and thickness. The settings are under line style - here is a quick example:
