That's basically what they've shifted to now. Each two month update cycle focuses on completing the "main" content for a girl (cell content and stripper/bordello content all the way up to the exhibition room), with some extras also being added in if they have spare time. Last update the finished Terra, the one coming out at the turn of the month will be Miss Martian, and then the next one will be Artemis (they plan to do this for all girls, but that's all the ones they've specifically stated so far).
