Some high-level comments. I think we should first figure out the general direction. Happy to chat, too.

Not a fan of abbreviations. Fan of "tor" :-).

I think a lot of the complexity stems from this function accepting non-empty ChangedRanges. I'd prefer to simply impose a restriction until this functionality is actually needed. Or do you already have a use case?

I think this interface is too complex and has too many assumptions. I think it would get significantly easier if it operated on a single file. Does anything speak against moving the "if (DoFormat)" below into the loop.
Also, while you can of course try to reuse rewriters ans SourceManagers, I think this makes not only the interface more complex, but also limits the possibilities for executing this in multiple threads. Why not just hand in the applied replacements and a string with the code?
