Aberrant Heritage/Illithid Heritage Feats

[Nada Rakshasa]

I've been reviewing the Aberrant Heritage and Illithid Heritage feats and had a question: Would it be game-breaking to allow the Illithid feats to count as Aberrant feats?

I mean, while some of these feats have scaling benefits based on how many you have, you also take a -1 to most charisma based-skills for each aberrant feat that you have as you become more and more monstrous.

Thanks, in advance, for any insight one can shed on this question.

Not really, seeing as the Illithid feats are horrible anyway.
