Bro is unfortunately too high level to this right now. There are a few things being worked on that might provide better interfaces for doing this analysis but they aren't functional yet. (bro script compiler and binpac++)

You could certainly write something like that. Our analyzers are abstracted in our repository so it should be fairly easy to see how they're constructed and to write your own, assuming you're comfortable with c/c++. We definitely recognize that falling back to c/c++ is suboptimal though, but at the moment it's all we have to solve your problem well.
