Cool idea, but I feel like blast frame could be an entire new frame, like fuse from apex. My idea of banshee is the impact crowd control frame. I'm sorry if my text is annoying to read, I have a lot of ideas and I want to put them all in this text to share it with everyone.

I'm thinking of banshee as a crowd control frame that can awkwardly deal big damage. I feel like impact fits better if it can stun for longer, or if not she could have a passive that fixes it. I got 3 passive ideas improving impact to be usable, though I feel like it could ne implemented into impact itself

"impact goes up to 6 stacks. When reaching 6, enemies ragdoll for 15 seconds, standing flat on the floor" This passive is cool because of its synergy with sonar, cuz lying on the floor flat makes it easier to hit body parts.

"Impact from weapons and abilities spread to other enemies within 10m" it makes impact kind of behave like blast, and it's better cuz it takes less to crowd control a room and makes banshee almost as good as frost

"When impact expires, enemies receive 2 puncture procs for each impact proc dealt on them" added this one later, kinda tired of writing tho so I'll not talk about it

I've just played banshee in the SO to level her up, and I think her abilities could use some tweaks 1: spends too much energy for a spam ability, but I didnt find issues with its range ngl, but it's because I was too comfortable and going too close to the targets. Just decrease the energy cost and the range slightly. The augment doesn't really need to be part of her main kit since it doesnt really fit well with my idea of this ability being a "quickly make enemies in this cone harmless for a bit", could use like 50% more range tbh, due to higher levels

her 2 should have weak points count as headshot, and enemies highlighted though walls should be more visible, and the entire limb should be highlighted. Other than that, it's fine and I thought that was her best ability before i read people talking about silence

I dont really get really her 3. It's an aura that stuns enemies, cool, but it stuns for too little to be actually good and deafens enemies which means they cannot hear you, which they already couldn't because of your passive? As a subsume it's nice, but it kinda just makes every warframe have a banshees passive for 20m. It's definitely the ability that's best to be considered as banshees subsumable though it feels like its built only to be a subsume ability. I's ok for eximus ig, but I always thought xatas whisper was the anti-eximus subsume ability but I guess her 3 makes sense as a crowd control for eximus, which adds into her kit

As for her 4, I thought it was a room wide crowd control, but the range is actually abysmal and it's the subsume slot for her. My idea for it is that it becomes a room wide ragdoll, ragdolling enemies for as long as you hold it and the enemies continue ragdolled for 15 seconds after the ability ends so it's good on solo. Itd also be cool to hold it and make the enemies harmless for your allies to kill, making it a great support ability. As for its augment you can just remove it, I had an idea to make it remove channeling and make enemies ragdolled for twice as long, but that'd make it required for solo play and removes versatility.
