Some sort of partition of North Rhodesia could also work. If Barotseland and North-East Rhodesia go independent (the latter of the two could perhaps be merged with Malawi), the remainder of North Rhodesia (which would contain essentially ~99% of the Whites of North Rhodesia, while only about a third of the total African population) would be about was White as South Rhodesia (roughly 7%) and could be a contender for minority rule.
Kenya, not Uganda (though admittedly, the "Uganda Programme" has to be one of the greatest misnomers in history) was proposed as a Jewish State.
Also, British Kenya was generally extremely elitist when it came to immigration (even more so than Rhodesia, which was quite restrictive itself). Much of the White population of Kenya viewed the country as a giant gentleman's club.
