Help me build a Strength based monk order

[pseudoasian]

Hello, ive been lurking for awhile and now i have a take on the monk class i'd like to share

Way of strength
Monks of the way of strength celebrate athletics and competition as a way of enlightenment. Monasteries are often devoted to gods or heroes of strength. Unlike the more ascetic orders, the way of strength embraces local communities and are often organizers of both professional and amateur sports.
Impossible physique
Starting at third level when you choose this tradition, your character becomes a paragon of strength and athleticism. His body pushes the boundaries of mortal men and bestows great power. When you are wearing no armor or shield Your AC equals 10+ your strength modifier+ your wisdom modifier, you have advantage on all strength and athletics checks, and advantages to save against poison and disease.
Signature Attack
At 6th level your character gains his own unique signature attack. The details are up to you, but the result is unarmed attack that costs two ki points. You make a single attack that receives advantage against the target and if it hits you roll damage as if you had hit with all of your available attacks that turn. For example a 6th level monk can normally attack thrice (or four if using fury of blows) a turn so he would roll all three (four) damage dice on the one hit. After using this ability it cannot be reused until after a long rest. Missing the target leaves the monk open and anyone attacking the monk receives advantage on their attacks.
Unstoppable fists
At 11th level your unarmed strikes have become impossibly strong. Your unarmed attacks score a critical hit on a roll of 19 or 20
God strength
At 17th level you gain the ability to accomplish impossible feats of strength. When rolling a strength check You can spend 5 ki points to effectively multiply your strength score 4X for the purposes of a single strength check. Your character cannot use this ability again until after a long rest

Notes:I made this order because i always play my monks as big hulking Olympians who fight hand to hand. I was disappointed when 5th edition made Dexterity such a vital part of making a monk. Sure you COULD make a strength based monk now, but it's completely underpowered compared to a Dex based one. I feel like i got a good start but i don't feel like its ready to play yet.

any thoughts?

It could be something along the lines of Sumo or Iron Body Kung Fu - study of ki has made you able to shrug off blows (Str and Con bonus); or some sort of damage reduction so the monk could take more damage. I picture attacks along the lines of bear hugs: grapples that do a lot of damage and can disable, fewer open hand attacks but doing greater damage, and throws - does damage and throws the opponent 10' or something similar.

i like the idea of a strength based monk though this feels very underpowered.
at third you are getting advantage in one skill and against poison and disease. also lvls 1 and 2 you will be very very weak as you are aiming for uigh strength instead of dex. they need something else for lvl 3, I'd recomend looking at the goliath race and barbarian abilities for inspiration.
lvl 6 seems almost like a disadvantage to use, instead of making 3 attacks which you might hit with some and miss for some you are rellying on one attack to hit in which you are spending 2 ki to get advantage for, considering shadow step gives you advantage for one attack for free as part of your bonus action ability this is very underwhelming.
lvl 11 i would have made this part of lvl 3 or part of lvl 6, fighter got this at lvl 3 and again seems weaker than the other subclasses.
lvl 17 has the way of the open hand either killing someone or dealing 10d10 damage for 3 ki cost, you are charging 5 for guaranteed grapple almost, guaranteed i might add. I would get rid of the ki cost and move this to an earlier lvl maybe.

i really like the idea of a strong monk however, this build seems very weak without even considering that dex is more commonly used as it is for initiative, stealth and your evasion ability and deflect missiles as a monk. this build needs to be stronger. i love the idea, however i felt like playing a goliath monk that still uses dex though took a lvl of rogue to get expertise in athletics instead. though a good attempt.
