Sure, but it's just pushing what 'magic' means. It's like the origin of life. If life originated somewhere else in the universe, and life on earth was seeded by a rogue comet - that doesn't actually answer the question on the origin of life.

My own solution was to make 'magic' super science through augmented reality, nanites, and sophisticated programming code aka spells. Then, super geeks back in the day opened portals to the Astral Sea, Elemental Chaos, and the Outer Planes, causing energies; arcane, divine, and primal to infuse the nanites with supernatural energies.

But anyone with enough gumption can work out how to craft a spell and get an augmented reality affect, if they so cared. There is a bit more of a cost than standard D&D; I still hate the idea of 'easy magic'.
