Just fill another LUKS slot with a randomly generated key file and add that 
file to your initramfs (which already resides on encrypted /boot, right?). If 
your distro cannot do that, you should probably fixing things there, not 
adding ugly hacks to the kernel.

Check how it is implemented in Arch, for instance [1]. I'm not sure whether 
this is currently possible with openSUSE, though.
