Let's keep it real the president of Somalia should always come from the main clan of the capital city. If non Hawiye wants the presidency then first look to change the capital
If so why continue with "Somalia" why not make it official and create Hawiyeland, your own clan enclave like Puntland and Somaliland?
The reason you won't do so, is so you can milk the international donors who still think "Somalia" is a thing

Somalia = NGO Paycheck.
