What's up Andrew. I don't think you can spin our pumps the other way. I may be wrong, but I can almost hear Grady rapping that in my head. The only chance you have of running it like in the above pic is by doing the same thing ... getting an electric pump. Are you sure your belt setup is like that pic you posted? I know I've seen yours in person, but I can't remember. All KB setup's I can recall seeing have the KB tensioner pulley to the left, just below the blower pulley. You could run the belt straight from the alternator .... over to the blower pulley .... straight to the crank. I just assumed this because I don't have pics to look at right now, but I do know that the snout sits over really close to the PS pump. The only problem I can see by doing that is that you won't have the "grip" that the blower tensioner provides. You will probably experience belt slippage that way. If you could some how get an idler pulley mounted in the area where your PS pump is, you could retain the blower tensioner and everything should work very well that way.
BTW, did you ever get that Fox you were lookin' at?
