I don't think panos have an alpha channel they are JPEG images.

It's correct that there's no alphachannel but depending on what you want to achieve there might be a solution.
But forget about doing it with PTP.
Using native krpano you can blend the entire panorama into another or you can use individual masks for blending whatever you want.
Also single elements can be implemented as PNGs that carry an alpha channel.
