It was stated to be device specific. Unless I'm missing something? I see no Motion file on the github. I only see the spirit, and op g. From the readme on the git.
"loki_flash" is a sample utility that can be used to flash a .lok image to an
actual device. It will verify that the provided .lok image is safe to flash for
a given target, and then perform the flashing if validation is successful. It
is also possible to simply use "dd" to flash a .lok image directly to the boot
or recovery partition, but using loki_flash is recommended in order to validate
that the .lok matches the target device."
So it looks for the target aka the specific phone.
So unless you have the file for the motion it won't work.
I see where it says its supported now, but does that mean he's got it up? Even if you got something to work we have no custom recovery besides the one we have, or kernel so why even risk anything at this point till we have these made?
