This is actually my preferred method now too.
Adding a slight delay to a copied guitar track can affect the stereo position (pan)
I (too) prefer to manually double-track parts that need a wide stereo image.
The subtle differences between the two takes creates a nice wide animated stereo image.
Much more dynamic/alive sounding that simply cloning a track and adding delay...
Stereo pitch/modulation/delay effects can also enhance the stereo image.
