yes, but it'd require a redesign or very special tooling.

that spacing between each mirror 'pedestal' is fairly deep, it'd require a very long end-mill or a five axis machine to be able to get into those crevices.

it'd be trivial to carve the needed angle into each 'mirror pedestal' , but the current design doesn't support the premise very well.. still, doable.

How about this approach. Just have a collection of wooden dowels with one end milled to be concave at one of 20 or 30 angles. Then you can assemble whatever mirror array you want by selecting and positioning the appropriate dowels. Or sold as a kit made out of plastic hex shaped rods that snap together.
