well ya know where to post yer doubts …
In fact lemme just say yer trick is awesome but I wouldn’t use it just for the fact that you’ll end up with a bassline that sits in the mix like a Lead, and it will take a he** of a lot of space… but hey if it works for ya the great! The audio world is certainly not just black or white 
Maybe I would use 2 bands with small stereo spread but not 3 and so much spread!
cheers,
