Yes the Machon HaMikdash, which has reconstructed most of the Keilim and the Bigdei Kehuna have modernized certain things.
For instance the Kiyor has an electric heating system and thermostat, it has different spouts that release different volumes of water so as to accommodate different opinions.
In addition the machon has created floor plans and bezrat hashem will install a floor heating system so the Cohanim will not get sick from the cold stones as they did during the previous mikdash.
There is certainly room for innovation, within Torah guidelines.
