Yes, one H.F. driver sounding slightly louder than the other could be bad capacitors and could even be dirty or worn out L-Pads. I think you've got a good plan--after cleaning the L Pads and replacing the caps, see if the H.F. drivers sound "identical" then. BTW, acoustics can also be a surprisingly important factor. If after cleaning the L Pads and recapping the crossovers one still sounds slightly louder than the other, try putting the right speaker where the left one is now and vice versa and see what that does.....
