Well, i did it last night. Pretty straight forward.
Rpi4b with samsung T5 SSD.
Did fresh install of AOP-8 on both media and followed the italians manual.
Boot time is ca 35 secs from poweron to AOP is loaded.
UI is VERY responsive.
Starting Kodi from AOP takes 1 sec!! Its finally usable
EDIT: not 15 sec boot, 35 when started from powerless state.
Seems there is a delay where PI is looking for an sdcard, before USB boot.
