Okay, I understood now.

First, multi-user.target depending on
/usr/lib/systemd/system/plymouth-quit.service to stop Plymouth, this service
conflict with graphics.target and will call "plymouth quit" at last,but graphic
target don't have this action.
That's the different point. 

So, If we want to port "multi-user" method to "graphics", we will copy the same
command to "graphic", but no other files.

So, If the "do the job" here means stop Plymouth in graphics mode: 
Yes, it can be done. and this work already be done inside Gdm for SLE.
but if the "do the job" means to solve this bug: 
I'm afraid it can't. because graphical.target wasn't be installed in this bug's
scenario. whatever command we put on the graphics.target list will not be
executed.
and you mentioned about Xdm, I think only when it be launched in "multi-user",
the stop action can work. but obviously, this is a violation of the design.

This problem will not happen in the scenario of the boot to character
interface(just like multi-user.target).
