If you really really want to try it, unzip the V2.2 and use files inside the src/install folder.
The install_komic.ffs is used by the kindle to perform the installation of Komic.
If you can read and understand all the install_komic.ffs file, than just use ssh to send those commands (and skip the part related to the progress bar).
Please note that I don't know if the folders tree is the same on the PW!
