It's not a Cathedral Window, but check out Daisy & Grace quilt as you go designs. They have various shapes and sizes. Jenny Doan of MSQC did a tutorial with their templates.
They even cut the batting with the template so it fits in each block. MSQC even sell precut batting. Or if you have an ACCUQUILT cutter there are dies you can use.
