I think that the biggest issue is that the pool was built on about 8 feet of fill that was totally unsuitable.
In my opinion, the design is critically flawed.
You basically have some structurally unsound walls filled with random dirt/sand/construction debris and then a very heavy load placed on top.
So, you have a pool being supported 8 feet above the ground on a perimeter wall that was never designed for that type of load.
Most of the wall is in compression (vertical force) and the wall is beginning to fail as evidenced by the cracks.
If the load shifts horizontally, the risk of catastrophic failure goes up substantially.
In my opinion, there's no way that you could find any engineer who would consider the current construction to be structurally sound.
Can a retrofit support system work?
Maybe, if it's done correctly, but I would want an independent engineer to evaluate the current construction to determine if reinforcements will work and if they will, design a proper plan.
I suspect that the current plan is the least effort possible to install some piers at the lowest cost then replaster and hope for the best.
