Fletching table for NEW ARROWS?

This might seem very modded, but i think it would be a great use that falls into combat and tinkering update. this update could add arrows, now i dont mean tipped arrows, i mean heavy arrows (fall quicker; adding a iron ingot along with the arrow) hard arrows (do more knockback; addinng coal to the arrow in the fletching table) quick arrows (fly faster but do less damage) slow falling arrows (really just fly until they hit something). The fletching table interface would resemble a crafting table, but maybe a 3x2 grid rather than 3x3, due to not needing as much space for crafting. The two hard parts would be balancing crafts (not using expensive ingredients like rabbit feet or phantom membrane, and the other would be arrow code (maybe? I'm not a coder).
Therefore this could add a whole new world of possibilities for the pvp community, and I'm sure the technical community would find uses for these arrows and targets, and for those just fighting raids.
Thank you for reading and considering community ideas.

also hire more mod developers for developing team, you might get some good ideas!
