Starmaker is a side project, the main project is Roundscape which will be fully focused after Starmaker's steam release, and there won't be any side projects for a period of time. All endings are getting reworked so yes, Charlotte will have some content.
In regard to Charlotte scenes on the page, Charlotte is not interested and advises that kind of exposure would only harm her business, the way in which those are shown in Anna's starmaker is kind of an overlook to be able to have them there in the list of pics for the user but we've talked about before during 1.8 and is most likely getting a slight change.
