There are multiple reasons not to use images (and only images) as navigational links. Aside from portability (image links and touchscreen? I think not), they're not recognized by search engine crawlers or screen readers. I would reconsider expanding if I were you. Navboxes are also not available on mobile because they don't transfer well to the small screen, and heat maps show they generally get little to no traffic.

Your wiki may be more desktop viewed (check in Analytics) but Google crawlers only check the mobile performance nowadays. It's not something you can just shove under the rug. UCP is not going to cram all the functionality of a desktop into a tiny screen.
