Saudi Arabia wank?

Apologies to the most holy custodians of the holy mosque for the instance of profanity uttered above. :cool:
So how could we, with a point of divergence between 1900 and 1960, make it so that everyone's favorite Sunni theocracy, Saudi Arabia, manages to control substantially more territories than the sandbox of OTL?
What sort of PoD would this require? Something like the French being more inclined to dispute the British in the Mashriq, allying with the Saudis in the process and butterflying away the 1927 Jeddah Treaty? Perhaps Ibn Saud's favorite son and heir, Prince Turki, not dying of Spanish Flu in 1919?
What sort of territories could super-SA have conquered assuming most favorable circumstances? Transjordan? Kuwait? Qatar and/or Bahrain? Yemen? Chunks of Iraq's sandy southern periphery?
 
Isn't OTL a bit of a Saudiwank, given how at the start of the 20th century they'd been driven from the Peninsula living in exile in Kuwait? Plus the British handed over 2/3 of Kuwaiti territory to them.


Perhaps the British completely abandon Qatar and Kuwait to the Saudis. North Yemen also could be seized, though it'd be quite the quagmire for them to hold the place. Their oil output would be 40% greater and their population would be 70% larger.

When decolonization comes around, Saudi Arabia seizes South Yemen but the British cut a deal to get a permanent basing agreement at Aden like in Cyprus.
