Of course he will - you can't have Keldorn in a party like that unless you patch your game...
I think it's a very good party the way you have it now - personally I wouldn't ditch Jaheira... You see, the problem is, there are so few neutral or evil-aligned NPCs in the game, that you have little choice...
The only other Neutrals are Haer'Delis (a bard) and Cernd (a druid). Personally, I wouldn't ever replace Jaheira with either of these.
