Yeah, I don't see a problem with that as long as they get the same stat as the JLI snipe rifle.
Right now the difference between JLI and Pathfinders:
*2 sniper carabines, JLI have 1
*Pathfinders are cheaper to reinforce for some reason
*Pathfinders can get zooks\bars, JLI cant
*Pathfinders vet values are a mess
*Pathfinders gets 55 vision on vet 1, JLI have no vision increase from vet and DPS increase starts to kick in only from vet 3.
JLI on the hand have better rec.accuracy and survivability.
But the main thing is - squads DPS are actually completely comparable, difference is minor. Main difference being that G43 on itself is pretty much carrying whole JLI squad because it can snipe models at higher health and has higher DPS then path sniper carbine and significantly better accuracy, meaning that G43 itself can deal enough damage to snipe models because it can focus fire 1 model.
Path on the other hand have 2 sniper carbines, 2 standard ones. Standard ones are better then JLIs kars, while sniper ones are much weaker in terms of DPS (and especially accuracy) then G43 and standard M1 carbine, on top of that 2 of them arent guarantying same model focus firing capability as JLI G43.
Point being, if we imagine that Paths get 1 sniper carbine (being simular to G43 in terms of damage\acc) and 3 normal ones, with the same snipe threshold as JLI, they will instantly become even stronger then the JLI.
