Modified keymap request

I was wondering if it would be possable to create a keymap that would allow
this keyboard to use all of its keys functionally.

I got one a few months back and in windows it just remaps the extras (like f11-f24) as shifted or ctrld combinations. I was hoping that it was possable to allow the keys to get unique scan codes that didn’t need to be piggy-backed onto other key combinations. I’m not overly familiar with keymapping, so is it possable given Haiku’s input server?
