Not sure why a Hellenistic civ in Central Asia/Indian Subcontinent would be any better?
For Civ 7 I'd be fine with this:
Greece: Represented by Pericles (diplomacy) and Alexander (militaristic)
Byzantium:
Egypt: Akhenaten (religion) and Hatshepsut (trade bonuses being essentially Cleopatra)
India: Ashoka and Gandhi
Mughals: Akbar/Babur
I think it would at least be fitting to give India the Greece/Macedon split for Civ 7 by giving them two leaders and then having a separate Mughal civ with the capital potentially being Kabul or Lahore instead of one in present-day India.
I've always been a fan of Classical history, especially the Hellenistic world, so I did feel like Civ 6 spoiled me on that front and do understand why people aren't that happy with the way the civs/leaders turned out.
If Macedon happened to be a one time thing, that's fine with me. I'd still rather Byzantium to stay it's own thing, separate from Rome. I'd rather a proper post-Roman Empire Italy take that spot.
