This is a job for...
Fubby!
Will post more as I hear of it. Also, I think we should exclude the ship model kit tie-ins, since the Aoshima Kancolle ships are basically remolds of the old WWII kits but other than the box label
(and more expensive pricing) it's only Kancolle merchandise by virtue of the girls on the box pic. Other than that they're not really all that related.
