Replace CPU to support Arducopter on FC

Is it possible to get a Flightcontroller with a not supported chip like the STM32F411CE, replace it with a supported one and do this procedere: https://ardupilot.org/dev/docs/porting.html, or are there more steps involved I’m currently not seeing. In particular I thought about a 4 in 1 esc FC (https://www.banggood.com/16x16mm-JHEMCU-GHF13-AIO-F4-OSD-Flight-Controller-Built-in-13A-Blheli_S-2-4S-4-In-1-Brushless-ESC-for-RC-Drone-FPV-Racing-p-1782009.html) for a whoop with Ardupilot support.

If I am understanding you correctly, you are asking if you can physically remove the microcontroller from that banngood flight controller and sodler on a supported chip?

If that is the case, the answer is absolutely not. I mean technically a very competent electrical engineer could maybe maybe maybe make it work in a very janky way if the stars aligned and the pinouts were compatible but you never would becuase it would take weeks of work at the minimum.

It would probably be easier to design one from scratch.

that’s what I thought, the only reason I brought this up is because i faintly remembered someone said it in a video I watched a few weeks ago but thought it was too good to be true, thanks for the answer!
