Occlusion for two surfaces in linked axes

I wonder if there is a way to render two surfaces on top of each other, so that the surfaces properly occlude each other.
In the following example you can see the standard behaviour:
[X,Y,Z] = peaks(128);
X2 = X(32:64,32:64);
Y2 = Y(32:64,32:64);
Z2 = Z(32:64,32:64)+1;
fig = figure(1);clf
axes1 = axes('Parent',fig);
surf1 = surf(X,Y,Z,'Parent',axes1);
surf1.EdgeColor = 'none';
axis(axes1,'off');
axes2 = axes('Parent',fig);
surf2 = surf(X2,Y2,Z2,'Parent',axes2);
surf2.EdgeColor = 'red';
surf2.FaceAlpha = 0.5;
axis(axes2,'off');
colormap(axes1,parula);
colormap(axes2,cool);
linkprop([axes1,axes2],{'CameraPosition','CameraUpVector','XLim','YLim','ZLim'});
The second surface is always rendered on top of the first, even if it not be seen at some points, due to being occluded by the first.
I can decrease the transparency of the second surface, but it leads to clutter and makes it difficult to see which surface is on top of which.
Is there some axes property that allows me to render both surfaces as if their data came from a single surface?

Thank you very much for the suggestion, this solved my problem.
I didn't know that 3d colormaps were a possible input to surf :)
