There is no reason why it would not work. I am currently running a 420mm Pace on my 29er. I needed the shortest fork possible that still fit a real 29er tire, and I think this is it. I am running it with a Rampage right now, and a Weirwolf will fit no problem.
I actually E-mailed Pace about it, and their only concern was with using V-brakes, as the 29" wheel would put the brake clamp right where the fork is designed to flex. I am using discs, so no issue here. I also don't think it would be an issue with the longer 440mm fork.
The fork has been great so far, very light, nice ride, and rockets up the hills. Now I just need some lighter wheels!
