Yeah, but "good old" has an independent phrasal meaning, as in "good old Charlie Brown". That's fine if that's what you mean, or if you want to play with the ambiguity between the two interpretations - but if that's definitely not what you mean, then best use the standard phrasing.

I don't think it's independent at all. I think it assigns the quality of good oldness to things that are good but not old. Or it refers to things that are good and familiar.

Yup. That's probably a better way to say exactly what I meant. "Good old" can mean something that's good but not old. "Old, good" means both old, and good. Thank you.

I suppose a comma might disambiguate, within a list of qualities, but I think my point stands.
