Some (tardy) shots from my contributions to the Italian-Hawaiian luau, thanks to all for the inspirations.
The two rubbed kalua-esque 4 lb pork shoulders, 7:30 AM:

Samoan poi before mixing, taro (
malanga from Tony's, close enough), coconut, and ripe banana (that's a slice of the malanga on the corn starch canister for the haupia, not pictured):

Samoan poi after mixing:

About 10 people out of 50 would try it, and they all loved it. Another item I targeted for a small audience (my dad), Spam and pineapple skewers:

The finished pork (taken out at 4:30, thought two smaller shoulders would go faster than that, no dice), on Italian fried dough (pittuli):

What would be even more entertaining would be the pictures of what everyone else brought, which included pizza bread, Waldorf salad, antipasto, and canned pineapple slices dusted with cinnamon. The theme was followed more loosely than I projected. The hosts did at least make wonderful salmon teriyaki with a great haul from a Lake Michigan charter earlier in the week.
Mahalo!
