A) Convert House civilian LF's into police cruisers, either by scaling up the models to HF sizes or reworking them completely and add a large version of a Deb as a kind of forward gun. Make a few civilian LF's into dedicated racers and one or two into specialised hyperspace survey ships/scouts.
The remainder I'd scale up to HF sizes but allow them to keep the cruise speed making them into interceptors that can still fight without being unhittable or undergunned.
B) Remove the class entirely, barring perhaps a few weaponless versions as scouts/racers.
C) Change them into some kind of hybrid fighter/freighter abomination
