Could you perhaps study and summarize the useful parts of those modes' 
fill-paragraph-function's outside of strings and comments?

Perhaps they are similar enough to what prog-fill-reindent-defun does 
already. Or perhaps there's some useful bit of behavior that could be 
promoted. Or maybe there is a specific step which differs in many of 
them, which could be separately made customizable.
