I know you discouraged me to « transplant » my working SSD Mojave 10.14.6 (Dell Optiplex 7020 old DAW) but it worked...
To resume, a big thank you for you Casey and all the people in this thread!

Hello, Patrice. Great to see your transplanting process worked. Transplanting a working MacOS installation from one system to another system is what I would have done in your position also.
When I decided to setup a Catalina 10.15.6 installation on my Z390 system, I did not try to directly install Catalina on it, but instead install using a blank hard disk on an old system using a B75 motherboard where the installation process went smoothly (using a USB stick created by Unibeast), and once I got it booting and working on the old system, I took out the hard disk and attempted to boot it on my main system using a USB stick. I adjusted config.plist and added/deleted kexts and drivers as necessary on the stick until I got it booting Catalina, then cloned Catalina onto the NVMe SSD in the main system.
In fact I did similarly for the older MacOS versions from Sierra onwards. I installed once and then cloned the working installation to my other systems.
Now I have gotten MacOS Sierra 10.12.6 / High Sierra 10.13.6 / Mojave 10.14.6 / Catalina 10.15.6 (with Supplemental Update) on my main system and my Z370 Coffee Lake system through this process of "install once, clone many".
