Random track variant

I have just purchased the most excellent VST Electri6ity for producing metal guitars. Usually, with a real guitarist, I would get them to play a track twice to get some variations in timing, tone and volume in the part, pan each one left and right, and use different amps and slightly different EQ to give maximum width. Now, however, I only have a single MIDI track, and want to send that to two Electri6ity tracks but with small variations in timing and velocity. Can this be done without having 2 separate MIDI tracks and / or a logical preset that fiddles with MIDI?
