I guess you could make some for the old daisy wheels, but it probably wouldn't make as much sense to make them for ones with the sweeps because the bricks would get in the way of using the sweeps.
You could "mod" the sweeps to go above the bricks, but then you would have an awful lot of friction wearing on your sweeps. I suppose you could also basically leave a huge swath of the bowl open for the sweeps to function in.
