That’s a great idea, but that is a huge project when there are some low-lying fruit that really need some tender loving care.
For example:
It might be a good idea to first consider updating the “Examples” Page and convert it into something much more glitzy (marketing-wise, it needs to really scream out what all can be done with TiddlyWiki), and rebadged as “Showcase TiddlyWiki Creations” (or whatever).
This page really needs to be front and center, needs some serious jazzing-up of the “wow” factor, and needs to be continuously updated (I.e. give it some life, because it looks dead and pitiful) such that people regularly take a look at it to see what is new.

However, like all things: spirit is strong, but flesh is weak. It takes people who have the passion and the time.
