Find a cyclops and bribe/mindcontrol/reanimate as templated undead and control/whatever you have to do to get him to help you. Give him a vorpal sword.

Have him select an automatic natural 20 vs Lucifer on his first to hit roll. Have someone standing by with a Limited Wish to automatically succeed on the attack roll to confirm the crit.

Snicker-snack.

The rest of the party is running interference with Wishes. Their job is to use the Wishes to get the cyclops into position to make his attack without him getting killed first, and to undo anything Lucifer does that makes that a problem.

PLAN STEALER!

It seems like a slightly more convoluted plan, though.

Darn! Thought I was onto something, and then the thread dies.

Umm... I don't know if this'll work because I haven't scoured Lucifer's sheet to see if he's immune, but here's my plan:

(assume the Samurai and Paladin are not already these types)

Have the Samurai renounce his order and become a Ronin.

Have the Paladin ask to retrain to a Holy Tactician.

Buff to make sure that the Ronin and Paladin win initiative.

Paladin uses Weal's Champion on Lucifer (whatever else is irrelevant).

Entire party devotes to making sure that the ronin can get a hit on Lucifer.

Ronin uses a +1 Vorpal sword to attack Lucifer.

He uses his Chosen Destiny ability to make the roll a '20'.

The Holy Tactician's capstone causes the hit to auto-confirm.

Lucifer's head comes off.

Is this win?

Edit: included paladin using Weal's Champion on Lucifer
