You are using the pccc decoder in an incorrect way. Please see attached corrected grc file: there are two ways to use the pccc decoder (i) either as a combo or (ii) in conjuction with trellis metrics. I have provided in your file both ways.
Regarding you second question about whether you can define your own FSM: Of course you can! This is the whole idea of the FSM class! Please read the extensive documentation on how to do that in: /usr/local/share/doc/gnuradio-3.7.7git/html/gr-trellis.html (or wherever you have your documentation installed), and let us know if there is something you do not understand.
