There's always the option of having a (largely) ceremonial president, usually elected by a non-standing representative body which is quite common in central Europe. It retains the role of a non-political head of state who represents the constitutional order and in theory even has quite a few powers should things go south, but without all the monarchy, blood based lineage, and pomp that at this point I think undermines the legitimacy these institutions have. Monarchy even if in many countries still around and reasonably popular is in my opinion on life support without any sort of modern justification for its existence. The Economist a while ago had a good column how the drama within the British Royal family with Megan and Harry is essentially a 'all that is solid will melt into air' moment as the family itself is gradually absorbed into something more like capitalist American celebrity-dom.
