Fist combat is already a thing in the games too, you can equip the Fist Ring and it turns your A and B into punches if they're empty. Of course in game it has no practical use other than to make the game more challenging. But this is because that's bare fists.

I'd save the Clawshot idea for maybe an upgrade though. For a start, maybe gauntlets that can equip seeds as ammunition?

Fire punch? Pop in an ember seed. Stunning punches? Scent seeds. Gale seeds for making that corkscrew extra spinny. 

And pegasus seeds? ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORAORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA ORA.

Later on you can equip it with little upgrades, or attachments, like a clawshot attachment, or a cannon attachment to launch seeds at enemies.
