Maybe in some scientific settings, but nowhere else. Why would it be logical to use a temperature system in every-day life who's base is set to a temperature that doesn't exist on Earth? Celsius and Fahrenheit are human-scale measurements, useful in daily applications. Celsius is a bit more logic-y, and Fahrenheit is intuitive.
I think I've got an even better idea, then. Make the carving the main attraction. Cut the shoots down after everyone's done, let it grow until it's tall again, and repeat the process.
You could make it play into some historical traditions of impermanence and cycles of death & rebirth
Call me crazy, but who cares? It's bamboo. Those names will disappear in about a week. Reinstate the entry fee, have a guy water-bottle-spray teens carving up the grass too much, and call it a day. It's not that complicated, nor a huge deal, it's bamboo.
