No, "an", not "on"

Gallia would be far stronger than you anticipate.

Can, remember that with the Empire divided, technology will go faster. As a general rule of thumb, the more nations there are in an area, the faster the technology will advance.

Now, with only the three states (and Persia) it won't be all that much faster than otl - maybe a few decades in most regards, somewhat more in the military - but it will happen. The Romans did quite well otl, for the most part, against the "barbarians." These guys will do better. Of course, it won't match otl rates after a few centuries, when Europe became so divided.

Huns would be unlikely to get further than otl, or last longer.

The thing that many people forget about the Roman Empire is that it was big. As a result, it was very rare - the exceptions were usually just civil wars - for armies from one general area to be moved elsewhere. Time is the problem, there. Atl, there is no such reinforcements anyway. But like otl, the local units should be able to handle things - and are likely larger in number, for that matter.

With a coherent and strong state in front of them, the "barbarians" would not get as far as in otl for the most part. Only in Gallia would they have any impact, and there they would become vassal-kingdoms, most likely. They certainly would not do what you're saying in Italy of the East.

The Huns would, Attila or otherwise, have the same problem as otl. When their leader dies, they are screwed. Only-a short term threat, and an exaggerated one in history too.

Migrations would not speed up, past the first couple decades. As a matter of fact, once the three empires get established, it's going to slow down - the decline of otl will be far less. China may even, after a century, see more attacks.

Now, all that being said, Gallia at minimum would stand a good chance at eventually disintegrating somewhat. Vassal kingdoms would try it, at least, at some point. The success would be debatable - there was areas in Europe that failed, and others that succeeded in integrating these realms.

And yes, your proposal is very OTL.
