Bag extensions or stretched bags for 24+ Street Glide - is anyone making them?

Can anyone tell me where I can find an either saddlebag extension kit (preferably) or stretched bags for a 24+ Street Glide? I bought a new 2025 SG a few weeks ago - it’s still at Harley getting add-ons, one of which is a 2to2 side sweeper type exhaust, which I love, and I assumed I would be able to fill the empty space under the saddlebags with an extension kit (or just pony up for a whole new set of bags. Now that I’m shopping for them, it appears nobody makes them! It seems like everything is for either pre-2014, or 2014-2023. Is there really nobody making extension kits or stretched bags for the new generation touring bikes? Any other suggestions?
