I know someone who has been operating a temple of Inanna and Dumuzi for decades (not a building, but regular group rituals). I'm happy to hear that the Sumerian deities are getting more attention. I took a college class in Sumerian mythology, and one thing I got out of it was that the Sumerians had a sense of humor. The story about how Inanna got Enki drunk while they were gambling, cleaned him out of most of his authorities as a god, and then had to beat it back to her home city before he sobered up, is hilarious.
