It might just have to. Move them all to a summary page and replace what's there with an explanation and pointer.
I've tried to retain a 'core' open inverter line of information, but also try to show the related projects in relation to it. Wikis aren't the easiest to style or layout, but they're not meant to be.
I think the trickier bit will be avoiding confusion between if say we create a Prius Gen 3 inverter page for the inverter info, and how that sits alongside the control board info.
