I don't know what you'd consider "sizable" but a lot of people these days are spiritual without being religious. Which is unsurprising. Atheism/agnosticism are on the rise, so it makes sense that people who believe in a god but don't subscribe to a particular religion are also on the rise.
People who believe in a god but aren’t part of a religion would have to dictate the parameters for their god in order for it to be meaningful in any way. As stated before, the OP didn’t make the initial idea that nebulous. They were pretty specific.
