2 paladins practical?

Is this a powergaming question or a roleplaying question? In either case, the answer is "yes," but for different reasons.

Obviously, in roleplaying, a paladin would seek to join with others who had similar views, thus, a second paladin makes perfect sense. Further, paladins being lawful and orderly, it would make sense to send out different types of paladins together to dispose of the opposition in a more orderly fashion and take advantage of the many strengths of paladin-hood.

From a powergaming standpoint, the general idea is to cover muscle and magic according to your preference, but to maximize the killing force either way. As long as you need to add muscle, why take, for example, Minsc, when you could have Keldorn? Neither one is better proficiency wise, Keldorn can wear the gauntlets of dexterity to negate Minsc's better dexterity, and Keldorn has the lovely side benefits of true site and dispel magic in the blink of an eye, freeing up your magic using characters for other spells. Further, on the powergaming mode, you can keep Keldorn as the two handed weapon wielding Paladin and make, say, your undead hunter a blunt weapon, two-weapon style machine. So, your party could be something like:

Protagonist (Undead hunter with, ultimately, Crom Faer (sp?) in the off-hand and flail of ages in the main hand)
Keldorn - Using mostly Carsomyr (with a halberd backup)
Anomen - Mace of disruption +2 anyone? Shield in off-hand, or, alternatively, have him use the Crom Faer in the off hand and have your main guy use long swords and short swords and use Arbane's sword in the off hand for the extra attack
Jaheira - Scimitars work fine, Belm gives an extra attack
Jan - need a thief (he's the only decent one) and he's a specialist mage as well
Imoen - Need a pure mage for powergaming. Robe of vecna and amulet of power to cut down casting times.

This is a nice blend of muscle and magic and does not suffer from too many paladins.
