You probably could get it all working but it will be a fair bit of faffing around.
Perhaps just getting a wing foil might be easier?
+1 iRigs aren't really intended for generating large amounts of power and aren't that comparatively big, either; more for beginner/kids generally. I've seen videos of kids foiling them, though. RRD used to make a compact windsurfing rig, not sure if it's still available.
btw, this review says the biggest iRig is equivalent to a 4.5:
