How exactly are you using this, do you change your top-level language to your new grammar, or do you include the grammar from the default LaTeX grammar?
Either way, I don’t think this can simply be done by adding a new grammar and some includes, instead the existing grammar needs to be changed to support this (but I didn’t look closer into this).
