It certainly can be done, but a number of things to watch out for of course. First, make sure you have spotted it EXACTLY where you want it, and then center it between two roof beams. To make sure no wiring is cut, use your Skill saw set to a VERY shallow cut and cut only the roof materials and the plywood.
You will then see the exposed insulation and any significant wiring. Cutting into the ceiling can then be done from the bedroom side. I might add, you should attempt to install two wood supports (beams) to firm up the framing and the vent itself. Installation and self-leveling dope should be self-explanatory. Let us see the photos of finished product.
