No.
From The Cipher Exchange:

I’m off to Cipher Clerk for this one.
Trying to think of possible 9 letter keywords…
Virtually gave me nothing. Neither did Invisible, or ideograph or abcdefghi…
Then I realized that Morbit relies on numbered input instead of letters.
Mission accomplished, K4 is not a Morbit cipher. At least not alone, it could potentially be used in combination with something else but as a single ciphering cryptosystem it is not a viable option.
I’d never heard of this one. Nice! I like this a LOT! I was actually thinking of something like this just the other day. I had a problem of dividing letters. But you don’t need to separate words. So you could modify it to use 8 letter keywords. You could even use some numbers for triple dots or triple dashes and things like that. Or maybe punctuation.
Thanks for mentioning this one.
