I went that route a while back and found a lot of weird little hitches. Keys that just wouldn’t remap and insisted on doing weird shit because of something set up in the factory ROM. Never mind the additional hassle of trying to get software to implement various layer swapping stuff if you want that - the QMK firmware has that built in. Sure, you could just pull out the existing hardware and replace it. Sometimes it’s easier to just start from scratch though.
