I'm not sure the original was macerated. More likely laminated. I would never go below this in a gear but there have been a lot of gears come and gone over the years and I expect macerated was an attempt at cutting costs.
Rick Freeman (Brazil Parts) comes to mind. Would they work? Yes. Would they work a long time? You're on your own on this.
Vince Falter has extensive discussion of aftermarket "high-end" metals gears, including one that was "timing adjustable."
