If Anwar wants to get the top job, he has to distance himself from the DAP. Only then can he be accepted by UMNO and the Sultans. The Chinese race can never become the government of the day in Malaysia. They have to face and accept this fact.
Most of Anwar's votes in parliament comes from DAP. With or without LKS endorsement, UMNO and PAS, both racist and religously intolerant, will not endorse anwar.
