You cant copy the look of clip B to clip A as there is no filter or anything applied to clip B that can be copied.
One way to attack this might be:
Put a shot from the good camera and the bad camera next to eachother in the timeline – a few secs of something representitive of each will do.
Use the 3 way colour corrector to remove the blue cast from the A clips using the B clip as a visual reference.
If the white balance was consistantly wrong this should be easier to correct as the error will broadly be the same throughout.
Once you have a setting that you are happy with you can edit your sequence, leaving the ‘blue camera’ as is for now.
When you have a finished sequence simply right click on your corrected clip and select “copy”
Then select all of your other uncorrected A clips and right click “paste attributes” and select “filters”.
That will apply the same colour correction to all of the clips at once.
You may find it easier to edit your sequence with 2 video layers. Put all the A clips on one layer and all of the B clips on another where possible.
That way its much easier to pick them out for the copy/paste process.
You could also use 2 different colour labels to make them easy to spot in the timeline if 2 layers is a problem.
You can also save the filter to your bin and simply apply it to any clips that need it as well but the advantage of the cut/paste is you do them all in one hit.
Obviously this would not be such a good method if you had a lot of variations in error or white balance but for a consistant blue cast its worth a go.
You can then tweak any that need adjustment individually.
