I’m nearly certain Acerbis stopped making silencers years ago, but the significance is; plastic-housed silencers did a superior job over aluminum housing for quieting dirt bikes back then, and quieting a 2-stroke engine is not that unlike an air rifle. So the perforated core-tube and packing used then and still used now, may work well.
Yes, I think it would make a good basis for a "hair curler" design. I just haven't felt good about any of those I have drawn yet. Here is a picture of the parts I am working with now.
Left to right, a baffle, a muzzle cap, and a base cap. The base cap contains a 1/2 x 20 UNF nut. I'll west system epoxy that in place during the print process for that part.
Baffles stack. They are epoxied to the sides of the tube and to each other at the four "redirectors". The code supports a one line change for diameter of the "can". I'm going to use PVC water pressure pipe to finish the prototyping and testing and then probably deliver using carbon fiber as the tube. Depends upon cost and weight. Even if I go with CF tube, I think I can deliver at below $50 US, free shipping to CONUS. PVC tube would cut that by about $10 so weight/cost are the deciding criteria.
The design is modular and I can replace/redesign any component independently. So 'bout done with development. On to testing

I am actually thinking about making the parts available individually. Maybe a DIY kit.
