This is simply not realistic IMO, you'd be paying thousands for two small fans and a heating element.

You can always just add fans and heating elements with switches to your seats, find a 12V power source and hook everything up yourself (heck, I already have my GM lumbar switches and been planning to install my own lumbar support for years ), but it won't look and function exactly as stock. Plenty of videos on youtube, or you can head on over to Gen5DIY and see their seat ventilation package install video, that should give you some ideas on how to approach this, if you really want heated/ventilated seats.

If you watch the illuminated door sill installation video I linked to above, you'll see that the guy installs it in a 1SS. That lighting package comes with the necessary harness, so no problems there.

Okay, but what about the door panels? is there a way to get those to work?

Sure, GM has several packages to address that, see screenshot below. Since your car is a pre-refresh 2017, these packages maybe discontinued or backordered, it may take a while before you're able to source them (I'd also try ebay).
