Yeah, that was what I was wondering about.It's grammatical and it makes sense but it's not natural, no. No one would say that, so it's no good.
What are you wondering? Whether you can use 'going to' after a passive 'be thought to' structure?
I'm afraid that would confuse most native speakers. You could say, "We think he is going to arrive tomorrow." Or: "He's supposed to arrive tomorrow."Is it correct to use "to be going to" in this pattern? "He is thought to be going to arrive tomorrow". The example is mine.
