I'm looking to recreate the MG 151/20 with muzzle flash suppressors from a 1/32nd scale BF110G nightfighter photograph. There doesn't seem to be anyone offering an after market barrel (Aires makes a resin kit, but no flash suppressors, the trickiest form of the array).

Would the 2cm FlaK 38 L/50 or L/65 in 1/35th work? Same caliber, but slightly different scale.
