For lonely seraphim-texture master wannabes;
Don't use paint.net, it doesn't use the right version of DXT5 and/or doesn't handle alpha separately from the other color channels. Whatever.
Also disregard my solution above, it works on some maps all depending on lighting, but there's a better way I think.
Use Gimp, isolate the seraphim pattern in one layer (however you want, I used paint.net addons), and then in another use your 'background' texture and change it's opacity to 0. For blender bakers, the background texture will just be the very dark stripey albedo bake that blender poops out. Then merge the layers, and export it using the BC3/DXT5 compression method.
