Telephoto lens in Rome

Hello everyone !

I'm planning to visit Rome during the first week of May, and I'm bringing my camera with me. Of course, I will take my 18-150mm and my 10-18mm lenses but... I would like to bring my 200-800mm lens.

Yes, I know that may sound crazy to bring a telephoto lens for shooting streets, buildings, monuments and ruins, but that would allow me to possibly take photos from an unusual and interesting perspective, don't you think ?

What do you think about this ?

Also, do you know any photographers that use telephoto lenses for shooting streets and buildings while being inside the city ? I'm not against more inspiration and tips :)
