Nah, only the monarchies have amounted to something (by large) in the modern post WW2 Arab world. So that would be counterproductive. "Democracy" is not really a perfect system either. Meritocracy is better and in many ways KSA already has that due to the majlids, tribes/clans, business class, religious class (although nowadays without much influence) + having a formal alliance and benefiting from it mutually. Without that ruling a vast country like KSA would be impossible.
Also have in mind that unlike most of the Muslim world, the GCC is the richest area of the Muslim world (by far) and the rulers (monarchs) provide for the people. Free healthcare, free education, help with purchase of land, housing, help during marriage and dowry, no taxation, world class infrastructure, sending talented students abroad (and less talented) for free and many other services that are unthinkable even in rich Western European democracies.
The problem is that they like any rulers, more so monarchies, are overly protective of their thrones and thus as a consequence cautious geopolitically. KSA was the exception but after the Arab Spring, KSA has adopted a more isolationist stance that I applaud as it has led to a rapid development in KSA, industrialization, opening up the country for tourism, attracting massive (on a world scale) sporting and cultural events, getting to host the World Cup, Asian Games, Formula 1, Dakar Rally, major tennis and ports tournaments, e-sports, music etc. Basically opening up the economy and country = more money to spend on infrastructure, military, overall development = less Saudi Arabians going abroad and spending huge sums of money abroad, = more expats spending inside KSA as most what they seek can be found within KSA nowadays. Not everything I agree with, personally I don't give a crap about so-called famous singers and what not, never attended a single such concert, but the sporting events and overall tourist projects (opening up heritage sites, Islamic as pre-Islamic, building world class beach resorts, island resorts, mountain, desert resorts etc.) is a good thing for the economy and people's well-being.
Better than during the dreaded Sahwa era where we had retarded elements (at times but it occurred) harassing people with music instruments and other stupidities that were introduced by hard-liners post Iranian Islamic revolution in 1979 next door and the Al-Masjid al-Haram seizure by terrorists.
Off-topic but you started it so I just wanted to write my two cents for what it is worth. You are free to disagree, it is just my opinion, you will find Saudi Arabians who want more reforms, less etc. But pretty much most like MbS a lot and what he is doing. Obviously he is just the figurehead but whatever made those changes (mostly focusing on our industrialization push) was long overdue.
