I don't think you're nuts...BUT (here comes the killjoy) I'm always very apprehensive about after market sun roofs. First and foremost, they are basically punching a hole into your roof and headliner. There is no guarantee the parts they will use is fully compatible with your vehicle. Would it even fit with a sunroofless runner? I have two 4runners in my garage - one with a sunroof (SE) and the other without (SR5). the SR5's headliner has more room since there is nothing between it and the roof itself (no motor, railings, hardware, etc.). How would the installers accomodate for this smaller space between to fit all the hardware? Another concern I would have would be fitting issues, would it seal properly, leaks, and allow for proper drainage? Something to consider before you tear a hole in your $30k+ roof.
