It's a good idea, but it's too late for that. I've said too much about the book under my real name.

At the time, I hadn't decided whether I wanted to use a traditional publisher, and traditional publishers hate pen names. You pretty much have to prostitute yourself on social media for traditional publishing to be an option these days.

I realized that self-publishing was the only way to retain the creative control this particular project works, but that was after I had talked about the project under my real name. I do agree that pen names are great for self-publishers, especially if they're trying to differentiate product lines or involve themselves in some of the most lucrative subgenres.
