Possibly the simplest thing to get done, is to have some agreement from HTC that it would be an improvement to change it. As, we are not certain if this is their intention or not, to have a higher degree of uncertainty.
After that, we have no clue how any change could be "patched" with the least amount of disruption to the current status quo or workload. One would hope that the shapes would already have some type of mask or alpha layer (I really don't know the correct language) that would allow for either a brighter/ shinier undamaged building or a much darker/ less reflective damaged building / rubble.
Smoke or haze would be something for a wishlist, but in terms of gameplay the added contrast is all that is required to distinguish targets.
