It is already possible to implement censors in chat, I've seen it but I have no experience in setting them up.

Editing the HTML, like CSS and JS? It is already possible to do on MediaWiki pages

Adding the search box to include other wikis would make search an extreme pain to use, as you would need to sort through what is on and off the wiki

Creating templates involves creating new pages outright, so I do not see how creating them through hitting the edit button or its associated drop down menu would help. Also, creating blogs off the edit button too does not make sense to me.

At least for custom 404 messages, there is already a MediaWiki page for that. If you want further customization, the dev wiki has code to add a background image to the create page box.

For the clock, the dev wiki also has the code to add it. It doesn't appear on the toolbar like you want it too, but it appears at the top right just under it.

What do you mean by Custom Mediawiki messages? If you mean custom notifications and stuff, you can edit them by going to Special:Allmessages, and typing a keyword into the filter search bar to help you find what you are looking for.
