it's still likely to sound weird. volume, delay and eq cues are used for perception of size, loudness and distance to a sound, and pitch modulation cues are used for whether something is moving towards you or away (e.g. doppler effect). slowly modulated short delays sound great, but they rarely sound like a proper doubling effect. unless the delay is too short, then it'll turn into a comb filter and it'll get weird.
there's a chart floating around that shows the psychoacoustic effect of delays from the 1ms to 500ms range, that's pretty interesting.
you really need an analysis/resynthesis tool to do it properly - formant mangling works pretty well.
