It definitely makes sense, especially as I'm assuming it would allow us to create 'original' spells and so forth that are more refined and less patched together. We've done it before, yes, but that was something we've only done when we knew each other's magic well. It's the magic that this world has never seen and can't be created with magic users of only one dimension that will help us the most against any magic threat. At least that's how I see it.
