Can SteemPress be sufficient for this? Ideally, it will allow anyone to set up whatever frontend they wish. Certainly SteemPress has more progress to make, but to my mind it seems like a really good approach because all the WordPress ecosystem can be tapped into, and all the Steem ecosystem can be tapped into, if the link between the two is sufficiently good. So, in essence, work on making a good link rather than on rebuilding everything that has been built so far in e.g. the WordPress ecosystem (CMS, templates, plugins, etc.).
