There no way around the donut hole except just don't twist the head until a donut hole appears.
A few years ago I used a can of clear coat engine enamel to lightly fog a reflector for a light orange peel of an extra reflector for an ML25 to compare to the acrylite lens. I ended up preferring the acrylite lens but that light orange peel reflector did help clean up the beam some. Throw was better with the acrylite.
Basically it involves spritzing a mist of spray paint over the lens and letting droplets of paint gentley land on the lens. The can is about a foot away horizontally and 18-24" vertically. Just push the spray tip breifly. Maybe twice. Let dry a while and try it out. Apply a second time and you're done. Anything beyond that and throw is greatly reduced.
BTW I did some test sprays to dial in the method.
