It is possible and has been done many times for custom kernel trees, but then you would need an I-pipe patch merged with the RT-preempt patch for the same target kernel. If you don't have such combo patch, then you will most likely have to apply the RT-preempt patch to a fresh kernel tree, without any I-pipe bits in, otherwise conflicts may appear at source level. > 2.
