It probably does a bit, in that it sets up the string to break smoothly over the bridge. Rather than look for a 12 string tailpiece (that will still be working on a principle of 6x2) you might look to get a block of brass or aluminium and machine it to replace the existing block on the tailpiece? If yours is anything like mine (no sniggering at the back there) the block that holds the strings is just held on with two nuts and could be a easily replaced with a block you've made (or had made?) to your own requirements.
