Whether your design takes up 512 channels on a single universe or 512 channels across 512 universes, you still only have 512 channels to control. So it's pretty irrelivant which version they license by. Also, if you're using fixtures in modes that use a full universe, then solo will still only allow you to use a single fixture (duet 2 fixtures or quartet 4 fixtures), you still need a bigger license.
Re-patching your fixtures for a show that would fit in a limited license (solo, duet, quartet) really won't take you very long on any modern console.
