Ability to climb on top of 2 high blocks

Ability to climb on top of 2 high Blocks

Jumping and then ledging to the block to climb. this would make the game way more dynamic so we dont have to build a block always. I dont want double jumb or ability to jump higher. I mean just climbing on top of 2 block high walls like on tomb raider or so would be nice. Alternatively it could also be an enchantement for boots. or the enchantment could be an upgrade so you could climb on 3 high walls.
