"I would like to have ATV4.1 in flash and HDMU on USB mini partition but I'm not sure if this configuration is possible or compatible"

...yes,work for my fine...
...install DuckBA for flash image with MAT 2.1 ( Morlys Admin Tool)
To have a fully operating ATV4.1 you must install DuckBA contained in j00ztalator 1.7e... in MAT 2.1 too...
otherwise you're unable to switch from ATV4.1 to another image in multiboot.
