Yes, he could. As for a civil war, depends on who fights who.

Not Armania. Too close to other areas already in use.

Hippodrome would still be around. Only reason it's not still around today is because the Ottos didn't take care of it. Their records actually have it being at least somewhat intact centuries after the fall of the city, despite it not being used or maintained whatsoever.

As of 2004, the city of Istanbul and the province of Istanbul are one and the same.

Further back than 1200, I'd imagine.

There is no reality in which either of those states would do that - the idea itself is ridiculous. And, quite frankly, the Byzantines would have it, hands-down.

No one in any position to beat the Ottomans by that point. And, imo, they were already a state on the edge of the empire by that Crusade.

Without the Ottomans, empire takes at minimum decades longer to fall, probably a century or two - if ever.
