The problem is that this more a flavor, I use a japanese keyboard layout and use the many thumbkeys in a "ergonomic" way. So space as enter and the enter button as end, that is not what everybody would want with such hardware. So again in short, yes I think if you can add custom rule files I think you should also be able to add custom hwdb files.
