Swapping won't work.
at the bare minimum, if it were possible, you would probably need to match exactly:
firmware version / revision
controller version / revision
nand chip part number
board revision
- hope that whatever bad blocks / bad columns are handled correctly
-hope no tables, config data etc are stored on the controller
-hope SSD does not instantly write anything to chips for whatever reason if things dont look right to its initialisation.
If I wanted data, the only way I would try this is to dump each nand chip first during the process while they are off anyway.
Marvell controllers are not dumb algorithmic controllers like Phison / SMI / Alcor. They are more like a microprocessor. There are alot of buzzwords used when they talk about how the controller stores data economically and safely, which translates to "hard to recover"

I want to buy another identical model and just replace the memories, my question is if someone has performed that procedure and if to effective result.

Unfortunately the translation is poor, but IIUC you have done no basic testing, yet you now plan to reduce the SSD to a pile of bits.
If you know how to use a multimeter, and if you can upload detailed photos of both sides of your PCB, I could mark the voltage test points for you.
