Is this feasible? What kind of possible obstacles?

aftermarket sunroof...easy

aftermarket moonroof...very hard

I was thinking moonroof, actually. Can you get this done at a glass shop maybe?

ill go take pic of mine with the headliner and ill show you how complex it is

you will need to weld the water tray up there, run drain hoses, get a new headliner to bend around it, cut a hole in the roof, and maintain a clean rounded edge

most aftermarket moonroofs when the glass is opened the glass goes on the out side of the car because of the complex headliner needed to hide the glass if it were to retract in the inside
here for a moonroof it cost about 700$ installed

Thats a valid point gameover, a regular sunroof would be fine for northern Alberta. The few days a year I get to use mine doesnt seem worth it too me. Actually I would prefer a regular one that I could pop open in the rear to vent. My stock moon roof is a bit loud to crack open.

Yea, the sunroof would probably be the route I would go, simply on the cost factor.

My buddy suggested that if I'm going to cut the roof anyway, I should someone to fab up a T-roof. lol.

I'd say do the sliding one. A popup one is kinda blah, and not as nice. It'* worth the extra hundred or so dollars.

here in MI a nice sized manual sunroof is like $400 installed a dual way power slider is like 1200.....
