It don’t make sense, most adblocker use the same sources, if not enough, most of them perm`ts to ad own filters, even from other adblockers. Aditional extensions can be other privacy tols, like script nlocker or fingerprint spoofer, like Privacy Badger, Canvas Blocker, JShelter, etc., and others like Link Unshortener, URL Cleaner, things like this, complementary to the adblocker. Use several adblocker only slow down browsing or even can breaksome pages.
