I get very pedantic about such things... do you think just uniformly expanding/shrinking the colour channels can do the trick? Especially when the amounts of CA is different across the frame and dependant on design (e.g. in the case of aspherics)?

In "normal" cases, CA is void in the center of the image, and gets worse and worse towards the edges, usually in quite an even way. Depending on the "offending colours", yes, shrinking/expending them, around the center of the image, can certainly do the trick.
Usually amounts of CA are not different "across the frame", other than getting more towards the edge and less towards the center.
