Just because the modern coelacanth looks a lot like ancient coelacanths, doesn't mean it hasn't changed in 400 million years. It is a different animal. Therefore, even though I understand your argument, it is invalid because the premise that coelacanths haven't changed is false.
That is one of the problems with many people attempting to understand evolution. Looks can be deceiving. Dragonflies from the carboniferous look similar to modern dragonflies but are totally different species. The same with gingko trees from the same period that are different from the one living species. I think much of this problem occurs by the term "living fossil."
