Not really - that is a fallacious argument, the data itself that would be provided by the ADS-replacement would not offset the data that is obtainable from the FSS - it is not a valid trade off situation.Partly because you were given that slot by FSS, you're asking for a shortcut away from FSS and that really should come with a trade off.
Also you claim that the FSS "gave a slot" is rather disingenuous - the FSS may be integrated but that does not mean there is any valid reason to credit wise penalise players for making a build choice to "have a module fitted". The inverse would be closer to being fair - penalising capability and/or credits for NOT having the unit fitted.
