Anything can be wall mounted. All you need is to buy or build a shelf. My original plan for CC's 1/2 busts was to buy solo shelves for their tiny imprint on wall space then place them with a certain pattern for looks.
Of course, there's the risk of stuff toppling over but it's a problem easily remedied by clear museum gel. Hell, I recommend the stuff on everything you want to stay put, even during earth quakes
