Sure! That’s the way a lot of people make stuffed tails. If you plan on stuffing your hood, just run a medium-light weight wire through the middle and bend away! If you’re not stuffing though that’s a little trickier because a single wire would 1) show through your fabric as a raised bump, 2) cause the rest of your hood to hang and flop downward from the wire. Stuffing is by far the easiest way to go but you may be able to experiment with using several lighter gage wires spread throughout the hood with a little bit of thicker fabric like fleece as an interlining layer to mask the bumps.
