I saw this on a Facebook post. A fellow has created a 1/2 rotax 912 and plans to make it a kit - buy his parts and stick the reusable 912 bits on it. Similar to the 0100. Claims about 50 hp. There are running videos, but none swinging a prop yet. Claimed dry weight is 39kg (86 lbs)...! Already there are postulations of using a big bore kit for 60+ horsepower. If he has this balanced right so it doesn't tear itself apart, and doesn't cost a fortune, it will be awesome. Spec sheet attached. Links below.
