Regeneration In Process
It's tiny compared to the Muslim world.
Maybe, but its not fighting the whole bloody Dar al-Islam, only a small fraction of it.
Dark Age is so... depressing.
Not for me.

They were supporting advanced civilizations in 1000 BCE at least. I'd imagine a unified state might be able to hold together.
The "s" in "civilizations" being the key, sort of. Infrastructure could be built up, but the terrain and thus the culture is quite diverse, there is a good reason few lasting empires were built there in the ancient ages.
Here's one to boggle your minds.
Alright... After reading what you posted thus far, I have come to the conclusion that the PoD is Central Asian, and involves a man named Yamin Al-Daula Abu`l-Qasim Mahmud ibn Sebuktigin. Or the absence thereof.
Then again, if South-East Asia means South-East Asia, that makes no sense altogether and thus is something else probably involving a weaker Ceylon.
Louis XVI was one butt ugly king.
Too bad for him, because we're talking about his grandpa.

It reformed its Government, Granting Hannibal the title of Emperor
Um... why would they do that? The most logical thing to do would be to kill him before he has any chances of coming back from the campaign; although, he could start a monarchist Barakid coup, in which case that works.
The language was integrated and influenced heavily by Greek and Latin, and would develop a language of Latinized Punic.
Not likely, the Italian provinces are rather backwards and faraway. You don't see OTL Latin being Poenicized just because Romans conquered Carthage, do you?
Emperor Hannibal was a very smart very wise strategist. He began securing the Trading posts of Carthage and establishing cities there. By 196 B.C.E, Hannibal had secured cities and colonies as far south as Senegal. Hannibal’s brilliant domestic policies
Not sure about his OTL domestic skills, but wasting money on expeditions and city-building "as far south as Senegal" is rather stupid of him, IMHO. Carthage didn't need any expansion beyond Western Mediterranean, if anything it could only be harmful to its basic interests.
Then in 163 B.C.E, an aging Hasdrubal wanted to have a legacy, so he amassed a large army of Carthaginian Infantry, Elephants and Mercenaries and attacked Egypt.
Any real reasons apart from "wanting a legacy"? IMHO Egypt would be rather untenable (too many new enemies, too easy to conquer, to lucrative for it to be ignored), and thus only a waste of Carthage's resources.
