That’s a very reasonable concern. But I don’t think your proposal describes how people use the term “conspiracy theory” most of the time. Note that the reverse can happen too, where people dismiss an idea as a “conspiracy theory” merely because it’s a theory about a conspiracy. Perhaps we just have to accept that there are two meanings and be explicit about which one we’re talking about.
