Switching Barrels

I'd like my cartridge conversion to have that Black Powder look (loading lever). Is it possible to take the barrel from my Cap & Ball Navy and switch it with my cartridge firing navy? Or would that be dangerous in some way?

You really dont want to switch barrels with out it getting properly checked for the alignment.

Otherwise it just depends. thats why i like the R&D conversion cylinder. as i shoot black powder round balls. then remove my wedge, the barrel. then remove the cylinder and replace with a cartridge cylinder then replace the same wedge and barrel
