Or lets throw a martial adept in the mix. Since not everyone gets multiple attacks, the warblades comparative power level shoots through the roof, since there isnt a tradeoff between standard attack and full attack.
Obviously the characters won't be of identical power; but they can adventure together ok using the listed stats (discarding extraneous stuff like skills & feats in the case of the 3e/3.5e PCs), certainly good enough for a one-shot. There's no problem with the 1e MC PC; you just treat it as a single class with the summed XP and powers of the MC. Converting from 3/3.5e is rougher since the 3e power level is different; C&C is best for converting from older editions.
