Many leaders forged large empires, Timur stands out for his brutal sackings, so I suggest to replace the first UHV of Timurid -Mughal to: sack a city in Russia, Hindustan, Western Anatolia, Caucuses and (wanted but didn't do) China. We have an option to sack in addition to raze, but none of the UHVs use that particular tag...
And here is another thought. Due to their military patronage of gunpowder warfare, Mughals were considered as one of the gunpowder empires of Asia, the other two being Ottomans and Safavids. The Mughal army employed heavy cannons, light artillery, grenades, rockets, and heavy mortar among other weapons. A special elephant unit called Gajnal were carrying Indian swivel-gun mounted on its back two of these kind of light artillery could be carried by single elephant. I can really appreciate Timurids starting with both Mongolian and Turkic element as exemplified by their unique units of Keshiks and Oghuz. Initial Timurid army should sport Keshiks, but Timurids-Mughals civ should not be able to build them, depicting the declining role of Mongolian-style warfare influence in greater middle East and India around those times. We simply need to pay homage to Mughal part of your new civilization, which lasted longer and was mightier. Sowar is a good start, I really liked them to represent formidable Mughal gunpowder cavalry. But I suggest replacing Keshiks with iconic Mughal Siege Elephants from Ghurids, who can get Mujahid unit from Sword of Islam instead. Or, alternatively, replace Timurid Keshik UU with 2 MP Siege Engineer unit from Sword of Islam -- on normal speed human player has only 20 turns to get 5% of worlds territory, so fast bombards would really help.
