Kundalini and ahrimanic yoga

I would like to ask you if those who practice kundalini yoga (according to the techniques of Yogi Bhajan) at a yoga school can also practice Ford’s Ahrimanic yoga at the same time, without any unpleasant “side effects”.
My goal is to integrate the light / shadow duality into Oneness.
What could I expect from Ahrimanic yoga practice? Have any of you already done this experiment?

I apologize for the English but I am not a native speaker.

Thanks for any replies.
