It used to be a common mod to drill more holes into the top of the airbox in order to get more airflow into the box.
If it were me, I'd leave it alone though, as parts are getting harder to come by nowadays and this is drastic considering.
If you wanted a quick test, just remove the airbox boot and see how the bike performs with no filter. This won't cause any damage if you ride it somewhere with minimal dust and for a short duration (like not years). It's not uncommon for people to not bother with air filters.
