HI @jamiemccardle Great question.
So, if I understand you correctly (based on the post and replies), you are looking to improve wayfinding of the content and improve content discovery without having to do a complete restructure of the community.
I believe this can be achieved by the introduction of custom 'wayfinding tiles' on home and category pages (and potentially nodes as well). These tiles by default showcase the community structure but can be changed to show specific pages or nodes as well (such as boards, TKBs, Blogs etc); giving users a direct path of access to these specific areas on your community. Please see below some samples and links below:
These are just some of my preliminary thoughts based on my current understanding of what you might want to achieve. I hope this helps. Thanks.
