The tetrarchy was a solid arrangement all in all, weren’t it for Costantine and Maxentius, it could have actually worked, but with those two power hungry warmongers kicking around there was no way it could survive me. I’d have ordered both of them to step down, otherwise I’d have declared them hostes. Does it mean civil war? Possibly. When Costantine began making a fuss, Diocletian did give in and made him Caesar, giving him just the legality he was asking for. I would have tried to put Costantine in place instead, it was still possible after all. If there’s gonna be a civil war anyway, I might as well bring in my charisma and prestige to win the day, I’m still the founder of the whole system and the strong man of the moment, aren’t I?
Agree,tetrarchy was not solid in the long run.How do you ensure that all future tetrarchs won't be the same power hungry warmongers especially long after you're gone? What is the guarantee they will respect the system? You have the option of appointing better people as tetrarchs from the outset, but how to ensure in the long run that civil war between the tetrarchs won't be as commonplace as the civil wars found in the principate? Or that one man won't like Constantine eventually defeat his rivals and become sole emperor again?
I’m sure that all of the barbarian magister militum were citizens as well(many of them were even patrician).Emperors will appoint barbarians as commanding officers no matter what.The loyalty of barbarian officers in general was not worse than that of native Roman officers.And unlike native Roman officers,these barbarian ones could not become emperor.You need to consider what might help, and what can be done. I'd have some ideas if I woke up as Diocletian tomorrow morning, but many of them would be rather foreign to the Roman mindset, and could easily cause a lot of trouble for me. Also: am I limited to ideas Diocletian (or a contemporary) would reasonably have come up with? Most of my ideas would revolve around setting up a proto-federal system of administration-- make it a pyramid-shaped design, rather than dividing the empire in any way. This approach seems best to me, but is totally "un-Roman". Am I allowed to suggest it?
In any case, no price controls. I'd write an easy-to-read tractate on inflation and its causes (to spread some understanding of the issue), and pass as stringent-as-possible laws against any and all coin debasement. The money must be sound.
No persecution of Christians. Edict of toleration, mostly based on what Genghis Khan would later do in OTL. (All religions tolerated, but those who try to harrass or suppress others get executed. "Thou shalt tolerate the ways of others... or else" is the guiding commandment.)
Implement a relatively simple tax system that taxes non-citizens more than citizens, and that taxes citizens' households less and less the more children they produce. The effect may be limited, but I would want to skew demographics in favour of Romans, versus barbarians. Citizens who serve in the military must like-wise be rewarded, tax-wise.
Put very clear limits of the ranks non-citizens can reach, both in the civil government and in the military. Any real command position must be reserved for citizens.

You cannot Romanian the tribes if they migrated in bulk and remained under their own chiefs while in Roman lands. The Romans lacked the ability to militarily break up large tribes after Adrianople.The specific goal is to make "Romanity" something absolutely woth embracing. I know that many peoples migrating into the Empire did this anyway, but the more you can further this, the better. There must be some sort of cohesion, a sense of a shared identity. Only such unifying ideas can ever keep an Empire alive. Once you lose that, it's game over.

Meaning that the tetrarchy will not work in less than perfect conditions?You do what Costantine and Valentinian did, the tetrarchy model with your family members in power. The only reason Costantine’s arrangement failed is because his second born and last born hated each other’s guts.
In Valentinian case, he died relatively young, Valens died in battle and Gratian and Valentinian II were both rather inept. An Empire’s stability is closely dependent on the emperor’s efficiency as such, thus I believe the best way the tetrachy could have worked was by having a ruling dynasty, each member of which with a fourth of the empire, and all of them capable enough, or if not, surrounded by loyal people who were.

Are you actually being sarcastic?
Which of Diocletian's reforms were good or necessary or beneficial? Which were harmful? What additional stuff would you change or not change were you emperor around this period, trying to rectify the problems of the Principate that led to the 3rd century crisis?
