An alternative to a sun pipe would just be a rooflight in the roof and a glazed light in your landing ceiling.(need to protect it) You then get the benefit of having natural light in your roofspace if you need to go up there. All my roof space has his a glass slate and that lets in plenty of light--so a proper roofwindow would flood the light in. There is an old stained glass window in my landing ceiling.
