I am not familiar with kmoon but I use the gkrellm moon clock. You can installed it via the gkrellmoon package.
GKrellM is a system monitor like Conky. Perhaps it is showing its age but it is usually one of the very first apps I install because without it it feels like I'm flying blind. If you don't want all of the monitors, you can disable everything and just enable the moon clock. I use a transparent theme (Pseudo transparency) which makes it look like the moon is just floating on your desktop (if everything else is disabled).
It has plenty of other tricks. I've attached a small tarball that contains 3 slightly different invisible themes. I have almost 200 themes installed but I much prefer the invisible themes because they work well with almost any bg image.
Here is a screen shot of it next to the default panel with everything turned off except the moon clock. AFAIK, the size of the moon clock is not adjustable.
