SCP Foundation

The Summary basically says it all. Is this a cool idea? Is it taken? Let me know down below.

First off, Pokemon is copyrighted, so using such an iconic aspect from the franchise may be problematic with the site's creative commons license.

I personally don't think it's cool—you don't define what is "a soul" in this context, or what you mean by "capture and replicate". Remember, SCP articles are written from the viewpoint of scientists, not video game streamers.

Furthermore, as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP object through observation and experimentation. You'll need to convince your reader that someone with no prior knowledge whatsoever of the anomaly managed to somehow figure out (not magically know!) all the information you've got in the article.
