Amazingly enough, this has been studied. A standard was developed. Tests to that standard were developed. Helmet models from multiple manufacturers (which curiously don't look like hockey or football helmets) are available that meet the standard.
Here's an example: the Giro Switchblade MIPS,
CPSC, EN-1078 and ASTM-1952-DH offering in just one of its many colors.
So if this appeals, knock yourself out.
