Just replace them with land value taxes that are assessed for each block or maybe the entire neighborhood. Then split the tax bill based on the area of land owned so that you get a fixed rate per square foot.

The "just replace them" requires rewriting/amending the state constitution again.

As long as property values are going up across the state, as a whole (of which SF is only a part of), voters tend to have a disincentive to do so.
