Moveable Holiday Obstacles

I just got my Halloween Headstone, and it's in a pretty inconvenient place in my village. Lots of people like to keep their Christmas trees, so I'm assuming if you can keep the headstones, people will keep these for decoration too. But it would be nice if instead of being obstacles that are stuck in place unless you get rid of them forever, you could treat them as decorations that are randomly awarded during the respective holiday. These special decorations would be able to be moved like any other decoration once you randomly reccieve them. Regular obstacles like plants and rocks would be the same immovable obstacles. But I'm sure lots of people would like to be able to move around their Christmas trees or Halloween Headstones. These seasonal decorations should be actual decorations, not obstacles. They're just too pretty. Thanks!
