Results of British & Russian war against the Ottomans in 1700s

In OTL, the British actively sought an alliance with Russia after the Seven Years War. Russia was interested, but negotiations foundered on the fact that Russia wanted Britain to provide protection against an Ottoman attack as part of the agreement. Britain wasn't hardline against this, but had enough worries it bogged down negotiations, and Russia eventually got bored.

But what if Britain was more worried about its international isolation and reluctantly agreed to such terms? Let's imagine that the Russian alliance put off France from getting involved in the ARW, so the Revolution is crushed and the French revolution is delayed. We then get an alternative Russo-Turkish war in the late 1780s, but with Britain on Russia's side rather than Austria.

I assume this would be a bit of a curbstomp of the Ottomans, faced with the Russian army and the British navy. Could the British succeed in attacking Constantinople from the sea and occupying the place? What would the peace deal look like? I imagine something like the Crimean Khanate to Russia, Crete and Cyprus to Britain, Morea as an independent British-aligned Greece, and Constantinople made a Anglo-Russian condominium.

Thoughts?
 
Those are big changes and the French would not be happy, but they'd find it hard to stop from actually happening.

American Revolution being butterflied away might be the most quibbly part of the scenario, of course. I am not sure there won't be another attempt or that it won't drag on, small-scale, even without the French.

Fair enough. But you think the result of the Ottoman war sounds plausible in terms of a peace deal? I don't have the military experience to know whether an occupation of Constantinople is viable. It seems likely the Brits could sink the Ottoman Navy, but would they have a force to hold the city versus the Ottoman army?
