You really need those .41s. You can have 'em and not be extended too far if you get all 4 revolvers.
If you haven't shot & fed a .41, then you are missing something unique to the revolver world. To my perspective, the .41 magnun is to large bore magnum as .38 special is to medium bore. It is one of the truly sweet shootin' calibers. And you can load for it cheap.....
