Thanks, I will look into this as well. I responded in another thread to someone who mentioned similar problem, I am posting below for others and any critique:

First step, you only need to do this once...Under Calibre 'Preferences->Interface->Toolbars and menus->main toolbar add Unpack book.

Then for each comic you need to do the following:
1. Import the Kindle AZW3 into Calibre.
2. With that comic highlighted choose Unpack book.
3. Select AZW3 in pop up dialog, hit Explode book.
4. After that runs, it opens file explorer to the exploded comic. Within Images subdirectory is the comic. There are other subs but I have no idea yet what they are or if you need them.
5. I would copy contents of images subdirectory to somewhere else as the directory you are brought to is a temporary directory which goes POOF when you exit Unpack book dialog.
6. Next, select all images in image sub, right click, select Compress to ZIP
7. rename zip to something meaningful and change file extension to .CBZ (Not sure if need to change extension or not, but I did)
8. close the Unpack book dialog.
9. within Calibre add the newly created CBZ file to library.
10. Connect the Kobo
11. Send that new file to the Kobo, eject and enjoy.

All that worked for me. The comic I tried it with was Dune The Graphic Novel Book 1. It is now on my Kobo Colour and looks great.
