There's logic there somehow (I suppose).
Have you thought that the act of swapping out the hands may end up damaging the eHobby Rodimus (the very thing that you're trying to prevent)?
I'd leave it alone to be honest mate, the clear plastic looks pretty brittle.
Did you want a Matrix to modify instead?
I'll have a look at home tonight and see if I have one laying around somewhere since I recall opening up two BiS sets - one's dangling around Galvatron's neck so I should still have a spare one somewhere.
