Installing power rear quarter windows

Hello, new poster here.

I just bought an 03 Grand Caravan SE, and my only complaint so far has been the lack of power rear quarter windows. I thought this was fairly superfluous before, but now I realize that it is a real hassle not having this feature. I was trying to find a conversion kit to replace the hand-latches on these windows, and although power conversion kits are available for the front windows, I can’t find anything for pop-out rear windows. Barring this, I may even consider trying to find some used and try to wire it in myself.

Has anyone else looked into this, or know if it can’t be done?

Thanks for your help!
