@the emboldened bit-Are you hinting at an EW conversion or is it a possible FTB for any other CABS' tech toys???
More to do with ELINT equipment. We are using them extensively in ELINT operations nowadays in addition to communication role also. Plus the avionics suite is upgraded and much better than what the original configuration sported. They underwent upgradation of the suite in phases along with the Dorniers.
