Disclaimer: this isn't an expert opinion (although I could probably get 
one for you if you want to go ahead), just that of someone who remembers 
the days of "electronically rechannelled to stimulate stereo".

As I'm sure you know, you can't produce true stereo from a mono signal. 
  There were two basic techniques: adding delay or reverb in the manner 
you mention, to obviate the impression of listening through a hole in 
the wall; and partitioning the signal across the stereo image.

One way of doing the latter, for example, was using high-and low-pass 
filters on an orchestral piece, so that the violins seem to come from 
one channel and the basses from the other.  (If used indiscriminately 
this technique could backfire: as, for instance on the rechannelled 
version of the Patience and Prudence hit "Gonna get Along Without You 
Now", wherein the pianist plays a run from high to low and the piano 
seems to go whizzing across the room.)

The best results I've heard with this technique were on Sinatra's '50s 
recordings.

But presumably, if you're editing dialogue, you could place the 
participants on different sides of the screen?  It would be a lot of 
work though.

Hope this helps.
