I did one a long time ago on a set of orphan drums with aerosol paint cans. I don’t have any pictures and they turned out ok but not a perfect match to factory style duco. I sprayed the whole shells the color I wanted for the center stripe (gold) and faded in the edges (british racing green).
I would recommend setting up some sort of lazy susan to turn the shell while you keep the paint gun or can steady. On a shell as narrow as most snares you might want to look in to an airbrush instead of a regular gun if you have an air compressor. Harbor freight has reasonably priced setups. If not look in to “art” type spray cans marketed for grafitti mural use that have a very fine tip to control overspray. I’ve heard Montana is a good brand, but I don’t have personal experience. Keeping a clean faded line without overspray on the edges will take a good bit of practice which is why I went from the outside in with dark over light but it does give a different look than traditional duco
