If you use icon group widgets, elevation is an available option, if "Fine positioning." Elevation is not available for icons placed directly on the grid, instead of using an icon group widget, but you can create an icon group widget that contains only one icon, place that where you want to, and make use of the elevation option for that single icon.
If you want to save battery by having no wallpaper, go to the Play Store and install Pitch Black: https://play.google.com/store/apps/details?id=com.tecdrop.pitchblackwallpaper

I've heard using a black live wallpaper saves more power than a black image. I'm not sure on the details of that though.
Y'all might like this app too.

Resolution with the website it links to can be anything you wish, app itself defaults to whatever your phone's resolution is.
