So we have 10 characters.
2 of us are going to NPC our guys to run an adventure that needs to last about 16 hours. (2 - 8 hour sessions)
We usually find, due to humor, that if we plan on 4 hours, we get 8 hours.
The overall campaign is a loose retrieval campaign where our characters are having to gather items for reasons yet unknown.
We need to gather two items in these two sessions.
We are ok with splitting the group since there are two DM's. We can keep them together some, I could DM for the other DM and some others while those sitting out play board games etc. Or The other DM and myself could each take 4 guys, put our own character with them and NPC them and do a lot of time with smaller groups.
Lengthy... I know....
So here is finally the question...
What adventure ideas could I do to get the best use of time and still have something that is extremely enjoyable and perhaps a little different?
Anyone have some examples of a two shot from the past that worked really well?

Characters Include
13th Elven Paladin
13th Air Wizard
13th Summoner
13th Bard (Dervish Dancer)
13th Bard (Detective)
13th Oracle of Battle
13th Rogue
13th Barbarian
2nd Rogue/ 6th Wizard/ 5th Spellwarp Sniper (3.5 edition)
13th Magus (Bladebound)
I play the Detective and the other DM plays the rogue so unfortunately a lot of the skills for these two sessions are in the hands of NPC's for all intents and purposes.
Any help is appreciated.
