Perhaps if you want to stay truer to the spirit of the system, then you might have zDog generate faux depth buffers for each of its shapes (using gradients when necessary).

Then you might still take advantage of Chrome’s “optimized” SVG rasterization, but also use the GPU to do depth compositing on the color buffer afterward. As a bonus, depth-fade intersection shaders could work (which are tricky with raymarching).
