I think you mean the "Haas Effect"
If I remember well it works from 13-24ms but I'm not really sure about that.
You should just try it out, but I think it won't work (well). I use a delay on one guitar when playing for fun with ampsims to get a fuller sound while tracking, but still get at certain notes some mono effects.
Try to place the mics to avoid issues or just work with them (see clayman thread)
