Doc,
You can always just use another hook. I'd suggest a very light wire hook so it doesn't effect the flies movement.
Tie your loop down to it with your hangback loop far enough behind it to swap out the hook. Once you have your loop tied down, cut the eye and point off. Basically all you're using is the shank of the hook.
You can then use the piece of hook shank as the tie in starting point for your bunny.
