this is definitely worthy of being explored -
In OTL the European attitudes were the French being pro-Muhammad Ali and the British, Russians and others (who were less relevant like Prussia and Austria) being anti-Muhammad Ali.
What would it take to mess with all this? Perhaps if France take a pro-Constantinople stand the Quadruple Alliance powers cut a deal with Muhammad Ali out of reflexive suspicion of France?
Or what if somehow Britain had decided stopping any Russian intrigues head-on was more important than stopping French. Only a decade or so after the Oriental Crisis, that is the direction the British went, and that led to the Crimean War. Wonder what it might take to poison the British against the Russians about 15 years earlier? Could Russia achieve some greater, earlier success in Central Asia, Persia or China that would give Britain the willies?
