I have one of those boards, and my answer would be no, the fins are too close together, so it would slow the board down.
But I did try my set of twins (Makani Walu2 16cm) with a stubnub in the middle (about 6cm), and to the rear of the box, and it worked pretty well. I borrowed the stubnub just to try it out, it gave me a little more upwind ability but not really that much, a little more solid tracking, but not really that much, didn't seem to slow the board down, but I never got around to getting one of my own. Being cheap, I thought $26 was a bit much for that little thing, which offered barely perceptible improvement. Other fin companies offer various versions of the Stubnub or Nubster.
