You have unlocked the ability to switch places using the ki in their and your body.

(This is a port of Way of the Boogie Woogie u/WaffleMage15 on reddit, his account being suspended for awhile now. there will be notes through out this subclass detailing things I could not add to this subclass either through it being impossible or me being unable to do so with my current skill level.)

Rugged Motion

At 3rd level, you can choose between your usual Unarmored Defense your AC equals to 13 + your Strength modifier + your Proficiency Bonus

(Publishers Note: I could not figure out how to remove your Dexterity modifier, if your Dexterity modifier is greater or less then 0, I recommend you give your self an AC modifier equal to the opposite of your Dexterity modifier)

Boogie Woogie

For the cost of a Ki Point, you may swap between yourself and an ally within 15 feet for as a reaction. If you or the ally are attacking an enemy, they gain advantage on attack rolls.

Heavy Hitter

Your heavy build physique makes your hits land harder, you now add your Athletics modifier rather than your Strength modifier when attacking or dealing damage with Unarmed Strike or Monk Weapon attacks

(Publishers Note: DNDBeyond Does NOT allow you to change damage to be based of a skill, so once again, this must be changed manually) 

Improved Boogie Woogie

Boogie Woogie's range has doubled to 30 feet. You may also spend 2 Ki Points to attempt to swap places with an enemy. The DC for this ability is a Wisdom Save equal to 13 + Strength + Proficiency, if you gain expertise in Athletics, double the Proficiency Bonus of this DC. If they fail, you swap places with the target and all attacks against them gain advantage until the end of your next turn.

FTL Neurons

A true monk knows that training ones mind is just as important as there body, you gain an Intelligence increase of 2 up to 20. For 3 Ki Points you may add your Intelligence modifier to your Armor Class as a reaction.

Revealing One Technique

The unhonorable guilt of hiding the effects of the Boogie Woogie from your enemy gnaws at you constantly, putting a ceiling on your performance in combat. The solution to this predicament? Just tell them exactly how your ability works before attacking them. So long as you haven't dealt damage to your opponent, you can choose to explain how the Boogie Woogie Works. Doing so removes the advantage gained from using the ability, however, for the remainder of combat, you can swap the postion of anything or anyone on the field with something or someone else for 2 Ki Points. Enemy target still must make a Wisdom Save.

Pinnacle

You've nearly at the Pinnacle for the Boogie Woogie, your experience until now has cleansed your soul and allows your mortal body to harness more Ki than a regular person. You gain 5 Ki Points to your maximum.

(Publisher's note: there is no way to increase max Ki Points so I can't fix this)
