Well, I think it depends a lot on what the plans for the radio are. If it is going to be used on a daily basis or sold to a non technical buyer then you are probably better off replacing off tolerance resistors with modern replacements.
On the other hand, if the radio is otherwise very original and will only tend to be played occasionally, them I see no problem repainting the replacement drifted resistor to indicate its current correct value. I have done this myself on occasion and have never had a problem. Another technique I have used is to parallel the drifted upward resistor with a modern resistor hidden underneath so the combined value is within tolerance.
I believe there is something to be said for preserving the original style components whenever possible.
