Party job planning advice needed

[Mithrankittycat]

I always look up to you importers on renkei, yokodama, jobs, ect. advice! X3

I'm definitely going to play with 4 other people with these final jobs:
White mage/Summoner - Healer
Bard/White mage - Support and heal and HP/MP regen
Black mage/White mage - Damage dealer
Thief/Ninja - Yokodama with paladin
Paladin/Warrior - Tank with a tail

Given that I'd have those jobs, I'm wondering between two types of character for the 6th party member:
Dragoon/warrior - Dark knight/warrior - Samurai/warrior (Doesn't matter which of the three, since they're all generally high-damage melee)
or
Red mage/warrior

This 6th party member would have emergency provoke in case the paladin and thief screw up (.....). With the red mage/warrior, we'd get the sexy red mage-exclusive spells like dispel and refresh. However, I'm not sure if we'd get through all the missions without a high damage melee person.

Would red mage, thief, paladin smackin'--and black mage castin'--do enough damage? ;3 Or should the bliss of MP refresh be sacrificed to replace the red mage with someone who hits harder? X3
