OR shd Meru, Aembu, Ambeere be locked just coz cousins have been huko thrice?

That's detail

here is a more practical proposition... just out of the box thinking. instead of focusing on writing laws for something as fluid as ethnicity - why not write laws to make the presidency much less a trophy or the results of a tournament? that's more future proof proposition - don't you think?

Blacks in US had to wait for over 200 yrs.
Maybe rotation can work over there.

That equation can not stand for ten years. Even Luo's and Kikuyus have been on the same side against Kalenjins at some point. It all depends on the main players. We however need to wean ourselves from this ethnic dependency and move to issue or ideology based politics.

irrespective of the system used, the presidency will be a preserve of the big 5 ethnics for Kenya's foreseeable future with the rare small ethnic president every once in a blue moon. its only logical given the big 5 comprise 60% of the population (70% if you include gikuyu cousins of meru, embu, mbeere). only the configurations of the tyranny of numbers will change. the gikuyu will drop to 3rd most populous community within the next 20-30 years but gema could remain the largest coherent voting block for longer than that.

even the united states has been unable to fully shake off ethnic block voting. i dont see any alternative other than diluting central government more by disbursing a larger amount of money and responsibility to the counties. though to be honest, kenya will be at peace as long as the 5 largest ethnics each have their turn in the presidency (president or deputy). with due respect, the small ethnic groups are not sizable enough politically to push through their objectives.
