My advice is to ignore the late game stuff. I don't think Mig researched anything past sorcery, but that was enough. FfH is about quick strikes, and you can wipe out a civ in a few turns.
A few counter arguments: Amurites are indeed very strong. Mig used the spellstaff very well in his game, using the second spell to make some key conquests. But he admitted that he probably couldn't have won without Q's gift of Air mana. You'd have to spend ~720 extra beakers to gain access to air mana if you follow in Mig's footsteps and use Divination as your stepping stone to Sorcery. I don't think anyone is going to gift you mana if you play as the Amurites. For maintenance, you can run City States civic and keep the city costs pretty low (City States got a pretty big boost in EitB compared to base FfH, and Aristocracy got a pretty big nerf). Another thing that Mig did well was to keep a bunch of swordsmen to act as attackers and defenders. He used Ingenuity for cheap upgrades from warrior->swordsmen and adept->mage; you'll need extra gold for at least the latter upgrades.
One thing I didn't mention about the Hippus: Aggressive is really helpful in the early game against barbarians. As RefSteel pointed out in the setup thread, you're likely to be dealing with goblin fort/barrow/ruins spawns on top of the normal barbarians (and, since the map is big, expect more barbs). The extra strength from Aggressive makes it more likely that you win against the barbarians, gaining more promotions. It also means you will probably have to build fewer units than other civs that don't have the Aggressive or Barbarian trait, giving an indirect economic boost. Note that if you border a Barbarian civ, the barbs will march through his territory to attack yours, so you can expect even more barbs than usual.
For Lanun: the boarding party may be weaker than other people's champions, but they start with some really nice promotions that more than offset the strength difference: Boarding lets you attack and capture other player's (or barbarians') ships, and Amphibious means you can attack from ships without penalty. Ships are extremely fast in EitB, and naval attacks are very hard to defend against. Plus, you can use AoE and/or fireball spells from on board to weaken the defenders.
For economy, I think one of Mig's biggest mistakes was not building enough cottages. Admittedly, he was running a lot of specialists and didn't have big cities, but I think cottages were part of the reason why e.g. coldrain had a much better economy. Since you're a BtS player, I imagine you're already aware of the importance of building and working cottages as soon as possible. mackoti in particular is really good at building a strong economy, and I think you'll need cottages to keep up.
