More enchantments for fishing rods

I have a idea for a few more enchantments for the fishing rod. One is sharp/shaper hook it would one make it so the hook would actually damage a mob if you hit it and two it would make it so after a fish bits your hook before it gets away you would have more time. Another one which is flaming hook it would cook the fish you catch and set mobs on fire that it hits or I mean I never understood this but I guess maybe it could fish in lava. I mean the fire one I am not fully sure makes sense but I mostly was just playing around with a fishing rod and was thinking how could I make this more of a weapon do more than just cause fall damage and kill the mob quicker.
