I believe you need to edit common_scanmap in utils.js, and potentially
atKeynames.js. You probably can infer the AT value from xev (and
pressing the key), iirc it's often keycode minus 8. The common_scanmap
index, I guess you can get it directly from the browser with a bit of
javascript (or some logging added to get_scancode()).

Never tried to look into what you are trying to do, but this is how I
would start at least :)

Key mapping is indeed one big complaint with spice-html5. I don't know
if we can guess which keymap to use from browser language and have some
hidden setting to override it, or something like that.
