It's really not that bad, you don't need Tier IV materia to complete the Novus and move on to Nexus. If you absolutely *must* have that Tier IV materia, you can continue to collect/save for it after you've completed your cheap Novus. When you've got enough to make the Relic of your dreams, you can remove the cheap/unwanted stats at any time (and only the unwanted stats, keep what you want on there) and replace them with the Tier IV stuff that you've been saving for. You can do this even after you finish your Nexus.
