Vegan adipose tissue

I always find that my plant based imitation meat lacks soul. Most of the taste from meat comes from the fatty tissue and since my seitan or tofu faux-deli-meat has no rind, I was thinking about the science behind actually making a plant based adipocyte matrix that holds the plant based fats, that could be infused with stuff like seitan to give it more flair, or something like that.

Any thougts?
