Hell. YES! Come on, if we can use swords we can infuse a bow with light too. I'd take them as a special weapon that could be a shorter ranged, lower rate of fire, lower magazine size, lower ammo capacity, higher impact sniper rifle with little to no zoom capabilities. It could be a great mid-to-long range weapon capable of OHKs that requires a lot of skill to use. Hitting a moving guardian with a bow when the projectile has travel time is a great counter to the OHK capacity of the weapon, especially when face-to-face with guns. Make the rate of fire slow enough, and anyone can outgun the bow--but no one can survive the hit.
