Turducken

Mr. Barefoot's friend's have a tradition of making a Turducken. Last year they did a TurGooDucken, but the chef has complained that the cost is too high and the labor too difficult, therefore this year will mark the return of the plain old turducken.
The first year I made baked ziti - pasta stuffed with three types of cheese sounded good. Last year I made peppers stuffed with peppers stuffed with peppers. (Red pepper, green pepper, jalapeno. Stuffed with a rice-pepper mixture.)
This year I could branch out - I could do peppers stuffed with stuffed mushrooms, but I need a third layer. I could do peppers stuffed with peppers stuffed with peppers again, but this year mix up what I use as filler stuffing. I'm thinking a mix of rice, quinoa, and cous-cous. There was some discussion of deep frying the peppers to add an extra layer. I am pretty sure this would end in disaster, my friend thought it was a great idea.
I would love to find a good way to mix sweet and savory in this mix somehow, but I don't think that is possible. I also want to mix flavors and textures. I also don't want to spend $30 on peppers again...
