There are a number of companies that offer clip blanks that can be drilled to suit just about any configuration.
Will it look awesome? Maybe, maybe not, but some popular companies offer clips that mirror aesthetics of a knife, but don't work very well, most everything is a tradeoff.
If you want to shoot a .338 Lapua, or a .50 cal, very few, if ANY muzzle brake configurations will follow the contours of the barrel and work well.....if you work with NO muzzle brake, you will suffer, and eventually, so will your point of aim...so aesthetics suffer from time to time, or you re-configure your expectations of what proper aesthetics will be in that situation.
Make sense?
