Probably not. It will probably be official weapons packages (i.e. dual 20mm pods under each 190 wing) rather than in-field modifications (like 6x50cal on a P-38, or 2x20mm and 2x12.7mm on a hurricane on the Eastern Front).
Mind you they've not said anything about any of these except the C-hog armament. All the rest is guesswork and debate.
