Blue Jeans' site mentions that the 4S11 is popular for biwiring, so it's certainly possible - and they offer that arrangement pre-made (banana to biwire banana, banana to biwire spade, spade to biwire spade, or spade to biwire banana) using the 4S11. The Belden stuff they offer is a larger gauge (either 10ga or 12ga), but the 4S11 is effectively an 11ga when you use two conductors for each connection so you are probably going to end up with similarly low resistance either way.
