There are a couple of problems this'll cause: first, it'll be confusing for users to be able to enter multilingual data in one place but not in the same field elsewhere. Also, it means that repeat authors will have to re-enter their additional languages for each submission.

Are you writing this just for master, or also for stable? There are a couple of things worth doing before you get too much farther in this task as a whole:
- Performance smoke test. Have you tried this with a sizeable install? It may have a visible effect.
- Assessment of the work required to back-port to the various apps (and OMP)
- Assessment of the work required to apply this to user accounts too, not just authors.
