Does this Stack? The PushMaster 5000

[Grixis]

I wanted to see if two abilities between the Monk and Fighter stack. Here's the breakdown:

Fighter - Battlemaster gets
"Pushing Attack. W hen you hit a creature with a weapon attack, you can expend one superiority die to attempt to drive the target back. You add the superiority die to the attack's damage roll, and if the target is Large or smaller, it must make a Strength
saving throw. On a failed save, you push the target up to 15 feet away from you."

Monk - Way of the Open Hand gets
"Whenever you hit a creature with one of the
attacks granted by your Flurry of Blows, you can impose one of the following effects on that target:
• It must succeed on a Dexterity saving throw or be knocked prone.
• It must make a Strength saving throw. If it fails, you can push it up to 15 feet away from you.
• It can’t take reactions until the end of your next turn."

If you're a Battlemaster Fighter/Way of Open Hand Monk, hit with your Flurry attack and use your superiority die, can you push the enemy back 30ft from the one strike?

....aaaaaaand here comes a thirty page post about whether or not an unarmed attack is a weapon attack.

"No, you can't parse the English language correctly"
"NO, YOU CAN'T!"
"CAN TOO!"

The answer here is DM dependant. If an unarmed attack is a weapon attack, your DM will probably allow it.
If not, your DM will not allow it.

they certainly can stack, but the thing you hit gets a save for each effect- meaning if they fail both saves, they do go back 30 ft.

I was hoping someone would see it my way. While they do have to fail two separate saves, a successful Stunning Strike guarantees they will fail both as Stunned creatures automatically fail strength saves.

I would argue they do not stack as written. Both abilities specify "up to 15 feet away from you" that means the ability can only cause a creature to move as far as 15 feet away. The abilities can't be combined to alter it to up to 30ft. Neither ability permits that. If they each pushed the creature 15 ft that would be different, but the "up to" clause while allowing smaller values also sets a max distance. This is the same as how mage armor recalculates ac rather than adding a bonus causing things like unarmored defense and mage armor not to stack.

How the dm rules it is another matter entirely.

I'd allow it, seems like a lot of work the long way around to get to what a warlock can do with a cantrip.

The abilities are incompatible since one requires a weapon attack while the other only works on unarmed strikes. However, nothing prevents you from using the attack action, attack with a weapon and use pushing attack, then follow up with flurry of blows and continue to push your target back (assuming it fails the saving throws). You will need to have enough movement left to keep pushing the enemy between the attack and bonus actions.

O.P it works with 2 separated rolls, and yes the US is a Weapon (Melee) Attack but its not an attack with a weapon (there's a big difference there)

It works, cause it its not a weapon, but it does work as a Melee weapon attack.

Errata:

Melee Attacks (p. 195). The rule on
unarmed strikes should read as follows:
“Instead of using a weapon to make a
melee weapon attack, you can use an unarmed
strike: a punch, kick, head-butt, or
similar forceful blow (none of which count
as weapons). On a hit, an unarmed strike
deals bludgeoning damage equal to 1 +
your Strength modifier. You are proficient
with your unarmed strikes.”
