Shove an extra fuel tank up the rear, upgrade the wing mounted guns to .50 cal and fit a few rockets to hardpoints under the wing and you have a useful type with good loiter capability for the Somali problem. Cheap to run and able to patrol the coastline and offshore danger spots in daytime to give a heads up of suspicious activity to ships in the area to enable them to avoid it or change course for night transit. FLIR equipment will give them reasonable use at night. Adapt as needed for similar roles.
May be worth a PMC taking a look at that option operating from shore bases in neighbouring countries with helicopter backup.
