Lol I thought the exact same, just with Israel instead of a steppe civ. Though I ended up with this:
Confederate States of America
(Jefferson Davis)
UA: Plantation Era
May not create workers, but may receive them when the city first expands to a tile with a plantation resource.

Trade routes grant

gold and

Planter points per each plantation present in the home city, in addition to increasing improvement construction rate by 5%(max. 30%).
UU: Planter
Replaces great merchant. May not perform any of its functions. However, it grants an amount of workers upon birth(based on era) and may be consumed for creating an Antebellum manor*. Alternatively, it may be used to sale slaves, consuming workers for a large amount of

gold.
UU: Blockade Runner
Replaces privateer. Radically different to it, the Blockade runner has 6

movement but does not have any of the privateer's unique attributes. Instead, it makes cargo ships departing from the city its stationed in impossible to plunder, and may be used to sell goods in foreign lands, granting extra

gold per each plantation in your territory.
*Antebellum manor: +2

culture, +2

gold. Adjacent plantations yield +1

gold or

food(depends on the yield of the resource improved by them). +2

culture after architecture, +2

gold after economics. 50% more yields during war.
Overall: a plantation based gold civ, with a slight wartime bonus. I think that it represents the confederate states pretty well...
