Changing the front interior light to have reading lamps w/o sunroof

[MacintoshGuy 14]

I've been looking at parts and want to swap my front interior light from the one that has the two reading lights in it but I can only find the dome lamp w/roof w/reading lights or w/o roof w/o read lights.  The only as I could possibly see to have the reading lamps without the roof is to order: 

42340974 Dome Lamp Assembly with Sunroof, with Reading Lights 

95443044 Sunroof switch w/o sunroof

 

I've seen a 2017 Spark with the reading lights and without a sunroof but the dealer didn't really want me pulling things apart to get part numbers, and there is no direct path for the assembly listed in the GM Parts sites.  Any insight that anyone can provide would be greatly appreciated.
