Recycled wool menstral pads/mama cloth

At the risk of getting too "too much information" on you all, I had an idea for yet another great use for recycled wool. I have been using cloth menstral pads, also known as mama cloth, for years now. I would never go back to disposables again. In addition to environmental reasons, they are just way more comfortable. Mama cloth typically is made with absorbent materials on top, and a waterproof/water resistant layer on the bottom. I have see that bottom layer made of pul (laminated cloth), fleece, and wool. I have never seen anyone use recycled wool, but I think it would be fabulous for the bottom layer, especially if it was lanolized.... breathable, moisture resistant, bacteria resistant, and insulated. Now I am not saying that this is an original idea, but I have yet to see it, and a Google search came up with nothing. If I were a better sewer, i'd try to make some myself.
