Why not? Unless you miss the cutting, stacking, bugs, bark and mess inside, and loading every few hours, you'll love it.
Coal is much easier with more even heat. Of course it depends on the chimney too. Get a good damper. (barometric)
Learn coal burning when it's below 40*f so you have enough draft since it takes lots of air moving up through the coal bed. You should be able to establish a coal fire within 1/2 hour, 15 minutes when you get good at it. Most make the mistake of trying to get a good bed of coals from wood and putting coal on the glowing coals. You need small kindling with flames, and sprinkle coal over it so the flames are ripping up through the coal. It will ignite easily and you continue to add more until the fire is covered. It's strange looking at a fire with no flames and it looks like you're killing a wood fire covering it with stones. You will only see a glow from the bottom up through the grate until it glows up through the pile and lights coal gas with a blue flame on top. The more air, the more blue flame. It can be frustrating at first, then you have steady 24/7 heat until you let it go out.
