no, it will NOT work
booting from a RAID was last supported with 10.12. It's been said that copying a 10.13 drive to a RAID would work, but you can't run updates and I seem to remember all sorts of problems - I certainly wouldn't trust it. That's when I left RAID booting. I haven't heard of anyone duping 10.14 or 10.15, but I would suggest that it would be a BIG waste of time.
