it is doable with HP and Attack stats, as long you can change the value and then search it again with current value. It should be possible to change attack stats with buffing your character with red haired girl (forgot her name, she's using MP7 weapon)
after initial search, buff your team, search again with current value after buffing
but again, it's useless againts armored unit that still have armor point, so what you really want to do is reduce enemies armor to 0, then shoot them with modded attack
it should be deal ridiculous amount of damage
as per changing defense, cover point, critical rate/damage, and mobility. haven't a clue, because there's no unit can fluctuate the value consistently rn
