I do not think there is any easy way. Packing in for the night now so a quick color exchange Colors -> Map -> Color exchange on a duplicate layer then a layer mask for background and windows...etc.
One problem is the specularity - the shininess It might be better to edit the blue first to try and reduce those very reflective areas.
Hopefully someone will come up with a better procedure. Edit: Save you hunting for the original https://i.imgur.com/FOt5MUu.jpg
