Making MNK slightly better.

[Rhyneth]

I've climbed into Crystal with Monk, I think it's fine numbers-wise outside of it's primary rotation so I'll address each point real quick with my very subjective and bloated opinion.

1. Remove knockback from Enlightenment and simply apply Pressure Point to target.

Actually no, the KB is very good in teamfights as you can push someone out of position which is VERY useful and slept on. You have three charges of Thunderclap for a reason, always follow up on Enlightment with Thunderclap and start harassing, it works just fine right now, no real changes needed. You can also use the KB to knock people off of high places and potentially kill them.

2. Change Six-Sided Star into a weaponskill (no change to current cooldown - basically make it work like Anatman does.) Remove the stun and give it knockback.

It's fine as it is, it's a stun that comes up every 15s which is really strong and if it was changed from a stun to a KB, that'd be a major nerf, we already have Enlightenment for the KB + Extra damage, you can Enlightenment into Meteodrive or Thunderclap into a combo if you want to KB and single someone out.

3. Make Earth's Reply activate automatically when you reach 20% HP and make it stun all targets hit by the compiled damage. On a 30s cooldown it would, at the very least, force enemies to burn their Purify. The stun would also allow the healing portion of the ability to trigger in relative safety.

I think it should just pop automatically at the end of it's CD. It should probably function more like Paladin's Holy Sheltron and apply Heavy to those around the Monk instead of a stun since Monk isn't about AoE stuns and that'd make it way too good and a must-have when it already has a lot of heavy AoE Damage in it's kit. It should probably provide 10% to 20% damage resistance whilst RoE is active to actually allow Monk to function as a hybrid dps-tank as intended.

4. Snap Punch should lead into another Blitz.

That sounds reasonable but the main issue with Monk's 7 part combo is that it does the following:

3000 > 4000 > 5000 > 3000 > 4000 > 5000 > 10000 (aoe)

It goes up and then down and then back up damage-wise which is very odd because EVERY other PVP class' rotation does not do this, personally they should just change it to.

3000 > 4000 > 5000 > 6000 >10000 (aoe)

Since right now a lot of people try to save their boosts for Phantom Rush exclusively and in reality Rising Phoenix is actually very spammable due to it's low CD, same goes for Enlightenment. As a Monk you constantly want to apply pressure and harass which your current kit allows you to do pretty effortlessly, part in parcel with it's fast charging LB.

I think if they made it so Snap Punch applied Heavy or was an AoE like Phantom Rush like you said, it'd probably make Monk a lot better than it currently is.
