No system will work
It will.
We need to have American style federalism and the government should offer tax benefits to any Somali that moves to a region in which their qabiil is a minority.
This will incentivise Somalis to move to cities in which their qabiil is not dominant to the point that each city will become a mixed city.
Then the government should institute legislation stating that a qabiil cannot make up any more than 30% of Xamars population.
Qabiil will exist but qabiilism will die.
Anyone who does not support this supports qabiilism which is condemned by our prophet SAW.
So you want to mix even the 1 qabil majority areas. You’d be creating future conflicts.
