Modifying OSM building height

I see a lot of example showing = new Cesium.Cesium3DTileStyle({

and modifying
according to condition.

I was wondering if I could modify or create 3D tile according to osm building geometry such as the building basis and modifying its height according to a value?

For example
height: {
conditions : [
// Any building that has this elementId will have height = 100m and height = 50m.
[’${elementId} === 68281927’, 100],
[’${elementId} === 68281872’, 50],

though it would draw the building with its modified height according to color style that would draw the building with another color.

thank you for all your replies.
