I've never come across one for that rocket but, I do know Vander Burn Rocketry has mods for other Estes kits and does custom orders. Maybe fire off a request by using the contact form (bottom of home page) ---> https://www.vander-burn.com/
Be aware that its a 24mm motor mount, so unless you upgrade that too, it will limit what motors will have enough thrust. Prob worth a sim to make sure you think its worth it. FWIW, i vacuum bagged carbon on mine and they are almost indestructible for significantly less weight than plywood fins.
