Haha okay here is some more practical bling
Instead of a muzzle brake how about a choke band.
A 2" long tube that has the ID cut on a taper of 0.005" over it's length. The widest part of the taper is the OD of the barrel and the narrow end is obviously .005" tighter. The tube is installed with the narrow ID at the muzzle.
The tube is heated to light blue on the iridescent oxide scale and the slide into place and allowed to cool. It will shrink the muzzle and give an effective choke.
Take it one step farther and thread the tube so you can install an air stripper as well
