I don't see anything like that on the github link in your profile, but I would be interested in taking a look if you have anything public?
As to whether I know any lawyers interested in that kind of thing -- I think your thing would face the same kind of issue that others in this thread have identified: why would lawyers be interested in a product that, at the end of the day, helps them bill fewer hours? You could argue that some law firm could use it as their secret sauce like Whatsapp used Erlang or something like that, but I don't think that the legal space has many people interested in this kind of innovation.
CSTML is just a serialization language so it doesn't have a repo. Like HTML its purpose is to embed invisible structure into a steam of visible text. BABLR is the main way we do this: producing the CSTML documents with a parser.
To the extent the law can be parsed as English you could generate CSTML documents by parsing the text of laws (or even writing laws in CSTML) but I think the "secret weapon" scenario is more likely in the present -- that a firm would use CSTML to show them effectively encode their current understanding of the structure of the text of the written law.
