I guess it's more about awareness since your works fully covering mentioned topics in them.
Touhou has no starter point to get dragged in (You can obviously start from touhou 2/6, but it doesn't really matter if you start getting intrested in touhou from written work or any kind of music since it leads to one thing - getting into series), and it really never needed it because it's like putting together a puzzle to get one image in result. It was always this way and even now, but touhou got distorted and ZUN really needs to do retrospection on his series to realise the things that made touhou as touhou and reappraise what he really wants for touhou. In realistic scenario he is only one able to carry this out, he needs to work only with people who actually care about touhou itself as series(opinion of a dilettante(who asked>?)). If there's manual work that can be putted on someone else i would be glad to help with this.
