Double run of speaker cables?


Just thought I would ask a question about a double run of cables from amps to speakers. I have two sets of cable from bluejean cables. I'm utilizing spades and banana plugs both sets are bi-wired. Have any of you tried this, if so what are your thoughts and experiences.

This would be feasible if cables were "shotgun" (non bi-wire) configuration. Don't see how to do it with bi-wire cables.
I have run "shotgunned" biwire cable configurations before when the biwire was not of sufficient gauge but  I eventually replaced them with a larger gauge biwire cable. By all means try it and go with whichever way sounds best.  
I experimented using 2 of the same cable to double up for a while and have now switched to a heavier 10 guage ofc copper cable with similar jumpers.  I think the 10 gauge sounds better, time will tell.
