Author / Category Subdomains for WordPress

I’m gonna open a new website on WordPress on which I wanna invest my full time, but I can’t figure out how to structure it the way I want. Basically, I want to create two factors to organize the content: the main categories, after called themes; the secondary ones, after called categories.

– mywebsite.com (static page that aggregates articles from every theme, organized in a way that they’re clearly divided)
– mywebsite.com/news (aggregates all posts with the category “news”) [customized logo that adds “news”]
– soccer.mywebsite.com (aggregates all posts with the theme “soccer”) [customized logo that adds “soccer”]
– soccer.mywebsite.com/news (aggregates all posts with the theme “soccer”, but only those with category “news”) [customized logo that adds “soccer” + “news” previous ones]
– soccer.mywebsite.com/news/articlename (standard unique url for an article on the website, no duplicates or anything like that)

After this, for some selected authors, I would like to be able to give them a unique subdomain:

– author1.mywebsite.com (author subdomain, more customized graphic (logo and background))
– author1.mywebsite.com/soccer/news/articlename (keeps only the customized graphic of the author, but keeps indications in the url about the theme and category of the article) [if the same article (or others written by this author in particular) is found in the archives of “soccer” or “news”, it won’t duplicate but it will follow this url scheme instead of the basic ones]
– Automatically customize the graphic of any link that ends with “?graphic=author1”, even to articles not belonging to this author, with the author1-customized graphic previously chosen.

I searched but couldn’t find an answer to my needs, because only outdated scripts apparently had the functions I need for my website. Thank you in advance to everyone that will help me!
