If I made a "Four horsemen of the apocalypse" unit of Chosen Chaos knights, which chaos god would fit best with each archetype?

White horse/Conquest (no, not 'pestilence' as that is a much later interpretation)

Red horse/War

Black horse/Famine

Pale horse/Death

I think:
Conquest = Slaanesh (fits the idea of an affluent and proud, conquering ruler. Also this is the only rider who has a bow rather than a melee weapon, suggesting a degree of refinement or subtlety)

War = Khorne (rather obvious here, khorne is the most martial god, and the horse is already a red horse)

Famine = Tzeentch (the actual text around this figure mentions that goods would rise to high prices, implying a theme of a harsh bargain on the background of events being engineered by a puppeteering power. also, the rider bears a pair of weighing scales, which feels rather tzeentchy - more prone to measuring/considering/manipulating things than direct action).

Death = Nurgle (nurgle is ultimately a death god, feeding on the energies of mortals at the despair they feel towards decay and the winding down of all things to their end, whereas his worshippers embrace the inevitable).

The only real alternative I see might be to switch Conquest and Famine respectively to be Tzeentch (again noting themes of subtlety and indirect action noting weapon choice) and Slaanesh (the text also says "but do not damage the oil and the wine" which might imply a theme of the wealthy and affluent lording it over those who cannot even afford basic food, and of course gluttony and selfishness are right up slaanesh's alley) .
