I deleted the kernel-aries folder and copied across the one from
samsung, renaming it to be the same. I hope this is kind of what you
meant? Then I ran:

source build/envsetup.sh
lunch replicant_galaxysmtd-eng
export ANDROID_JAVA_HOME=$JAVA_HOME
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks bootimage

Which created a ramdisk.img at out/target/product/generic/

Which I then flashed with heimdall.

Now the samsung logo appears and just hangs, but the phone doesn't
reboot automatically anymore, not sure if this is progress?

Please let me know if I'm on the correct path, or what I should try and
do next with it.
