Orban 275A, ftp://ftp.orban.com/275A/ , or the Orban 245, ftp://ftp.orban.com/245/ , these are cool and are pretty much phasers.

Yup.  In fact in the 80's, Philips (among others I'm sure) was marketing stereo-simulator chips, and that's essentially what they were, as were all those simply awful vinyl discs marketed as stereo-processed-from-mono. Stick a bunch of notches on one channel and stick a bunch of peaks ont he other where the notches went on the first channel and the two channels are, um, "different".  Not particularly effective or convincing though.

 Here's a couple attempts at what you're talking about(from the "Polish" schematic site someone recently posted):

http://tremolo.elektroda.net/tematykanf.php?adres=Efekty&plik=Efekty/Retrostereo.jpg#schemat (http://tremolo.elektroda.net/tematykanf.php?adres=Efekty&plik=Efekty/Retrostereo.jpg#schemat)(this one uses the Phasing method mentioned earlier)

Other than that, there are a few freeware VST plugins, but who knows what they do or how they do it.

yes, Philips did the (now discontinued, IIRC) TDA3810. Can be had cheap, lately, due to RoHS...

Elektor magazine had a nice project ~25 years ago,
with a bank of (16 ?) parallel differently tuned bandpass-filters,
whose outputs were routed alternately to the left/right.

Very impressive!
