Rig master I am not but will offer my thoughts on this one.
First off looking at the crank i can maybe see where beanz problems came from with them, I would hazard a guess that the hook lacks movement in the mouth and gets its hold via a very nasty grab and twist movement so i would go with a different hook pattern like you suggest.
I presume like Nick suggested you are going to whip a soft hair material on for the hair
For me a stiff section and long hair are very inefficient as IMO it restricts the movement of the hook in the mouth, for me stiff sections work better with the bait closer to the hook either D rigged or via a hook ring swivel on the shaft held by a bead (not sure well this would work with a snowman untested but works fine with a wafter or pop up).
This is what i am currently playing around with
In this example the hook bead is set to high (only realised after taken the pic ) and is set for a pop up, but you can use it with a wafter by sliding the bead closer to the eye, on the bottom it sit with eye slightly cocked by the buoyant bait leaving the hook point heavy so no matter which direction the bait is picked up from the hook will point down into the hooking position and the little bit of exposed braid should give it enough to grab hold (in theory ). The hook is attach to the eye with a grinner with the coating still on so it kind of extends the shank, also the coating is left on for the section under the shrink tube to help it hold its shape.
The above was designed to give you a couple of things to think about rather than this is the way you should go.
Now for your rig you were going to attach a separate supple hair would it not make sense to tie the hook on with a conventional knot rather no knotting it to the shank and then whipping over the top again, I have found this makes the section round the eye very bulky.
