Currently, in Minecraft, you can simply make a 2 block opening, to block off Wither Skeletons, which can only enter through 3 block openings, from reaching the player. It would be funny and interesting, given that they are intelligent mobs, if they crouched down to go through 2 block openings in order to reach the player. Their AI would have the ability to detect 2 block openings but only when aggroed. They would do the crouching animations that the players have.
