I don't think it's a good idea to replace him; they have different personalities, statistics and alignment.
I have to agree with Andyr, Kagain may be gruff but he's not as unpleasant/nasty as Korgan. Using Korgan's dialogues would serve to make him more like Korgan than Kagain.
Bring him in by all means but, and this is only in my humble opinion, if you have the time that it will take to develop him as Kagain. Time is not an issue for me but I understand that not everyone has this luxury in RL.
