As I said in the post, I'm not very technically minded so I'm probably not the right man to propose a solution but if someone wanted to set themselves up as an editor they could set up a designated email for steemit and receive submitted for edit posts in that way and once edited they could be emailed back to the creator of the post. In this way the creator would then be able to see exactly what coding has been done to achieve the desired presentation and should then have a better idea of how to go about doing it themselves in future!
