It has been tried - in Iraq the yanks took a pair belonging to NASA and modified them to see if the concept had legs.
They are still being used by (IIRC) the Phillipines - very capable aircraft. But definitely not for anything like near peer - I always thought that the Argies are missing a trick with their Pucara. Although not
that modern they seemed like a capable platform for COIN - with a semi-decent MAWS and DIRCM it could hold its own against most MANPADS.
There was an episode of the Fighter Pilot podcast that talked (again IIRC) the Bronco and touched upon other types used for the same mission.
In case you have not hung around our crab brethren:
MAWS - Missile approach warning system. Usually only passive in nature.
DIRCM - directed Infra-red counter measures: A freakin’ laser that blinds the sensor of a MANPADS
MANPADS - man portable air defence system - a stinger type thing.
COIN - counter insurgency
