Pickaxe Enchantment meant for mining!

So here me out, imagine you see that iron near lava, and you said "Oh Boy! I really need that iron but don't have any convient blocks at ALL to my disposal, and my pickaxe is about to break!" But, what if there was a pickaxe enchantment that if you're in a 1-2 block radius, it automatically goes to your inventory, but raise it up a level, "Auto inventory enchant thing II" and it's a 1-3 block radius, but now let's fear ourselves. "Auto inventory enchant thing III", where it's a 4 block radius. The enchant can work like, when you mine the iron, it calculates where you are, makes itself a invisble path, and it just ZOOMS to your inventory, or just automatically. But, we can't have good things in life. If someone is standing infront of you, it goes to THEIR inventory, same works with something like a Zombie, where they hold it if they are not holding anything. If there is a block that covers half your character, that's fine, but if it's 2, it just works like any normal pickaxe and it just falls. This could work if a Zombie is already holding something. It won't work through lava since it goes to YOU,  so it'll just burn, but if it's not BURIED in lava, it should work fine. Obviously this is about Pickaxes, but this can maybe work with swords, where if you kill a player their items go to you, and same works with a mobs drop loot. No clue what this echant should be called, but thought this was a neat idea I thought of.
