Idea: Changing Boss Weapons Ashes of War to combine several moves through Stances (Explanation inside topic)

[BiancoAngelo]

First off: English is not my main language, so I might sound a little confusing, but I hope I can get through what I am thinking about

My idea is to make Boss Weapons have stances for their Ash of War to give you access to more Boss variety with a single weapon.
Instead of using actual Boss moves though, it can be actual Ashes that are avaiable already, just slightly tweaked to fit the weapon better.

For example:
Starscourge Greatsword: Hold L2 to enter a Stance.
Press R2 while in the stance to use "Starcaller Cry", pulling in enemys with a shout, and then press R2 again for a followup AOE Attack by slamming the swords into the ground.
Press R1 while in the stance to use "Savage Lions Claw", press R1 again for a follow up attack.
Press L1 while in the stance to use "Spinning Gravity Thrust", press R1 again to use a follow up attack.
(Note: Yes, I know he technically only used (Savage) Lions Claw and Spinning Gravity Thrust during the DLC encounter, but I think they fit the original Weapon more due to the Gravity theme.)

Greatsword of Radahn (change basic Moveset to Great Curved Swords, it fits the weapons better): Hold L2 to enter a stance.
Press R2 while in the stance to use "Lightspeed Slash", Hold R2 to charge the attack.
Press R1 while in the stance to use "Promised Consort", press R1 two more times for up to 2 follow up attacks.
Press L1 while in the stance to use "Blinkbolt: Twinaxe" (maybe change the name into "Blinkbolt: Twinblades" and give a holy effect instead of thunder), Press L1 again for a followup Spinning Attack.

Maliketh's Black Blade: Hold L2 to enter a stance.
Press R2 while in stance to use "Destined Death".
Press R1 while in stance to use "Black Blade" (The incantation, but as an Ash of War used with the physical Blade instead).
Press L1 while in stance to use "Blade of Death" (The Ash of War from the Black Knife).

Hand of Malenia (Change the R2 to the double Slash from the Serpentbone Blade / Blade of Night Katana): Hold L2 to jump into the air and enter a stance.
Press R2 while in stance to use "Scarlet Aeonia".
Press R1 while in stance to use "Waterfowl Dance", press R1 two more times for up to two follow up attacks.
Press L1 while in stance to use "Scarlet Rot Wings" (A variation of "Aspect of the crucible: Wings" that uses Malenias Rot Butterfly Wings instead of the crucible wings, and skips the jumping animation since the stance already puts you into the air). Will Buff the Weapon with Scarlet Rot for 30 seconds (and changes the Waterfowl Dance animation to that of Malenias second phase version).

Those are only four suggestions that came to mind, but I have plenty more in my head already, but I just wanted to ask if someone is actually able to make these, and if it is possible in the first place.
And while I mainly think about Boss Weapons, it would also be cool to have such Stance Weapons for some non Boss Weapons too (so that we can at least have one such weapon for every weapon Type.)
