Yes, religions will almost always maintain a position that retains their previous "correctness", but if you could make a "soulless simulation" that is indistinguishable from the "real thing", it'd make a lot of people scratch their heads and say "wait, so what role does the soul play here?" ... it would seem to make the soul redundant. (Of course, that feeling of the soul's lack of necessity has already happened for most that have any knowledge of modern neuroscience.)
