It's an interesting thought experiment. You would definitely need multiple versions as there is disagreement on what foods qualify as "raw Paleo" and different people fare differently on various "raw Paleo" foods.
My triangle would probably range something like this (from the apex--smallest amount--to the base--largest amount). I would put some value on freshness and avoidance of pesticides, preservatives, etc., so the sizes of the tiers would vary depending on what was available locally, organically and in season.
(All foods are assumed to be raw, with the plants being organic, and the meats/fish being wild or pastured)

OPTIONAL TREATS: Tree nuts, raw comb or hand-packed honey (preferably including grubcomb, if possible)
OPTIONAL: Fruits (with emphasis on those low in fructose and overall sugars)
OPTIONAL: Brassicaceae (except for those that are inedible or nearly inedible without cooking or refining, like maca, Brussels sprouts, kohlrabi, turnip, swede/rutabaga, and rapeseed), roots (those edible without cooking, like carrots, celery and onions), herbs and other plants relatively low in toxins
OPTIONAL (but recommended if diet would otherwise be low in iodine and magnesium): Seaweeds (protists), young leafy greens
Fish, shellfish, sea mammals, seafood, eggs, small mammals, insects, snails and other secondary meats (including organs, eyes and small, chewable bones)
Large land mammals (including fats, organs and blood or sea salt)

I guess mineral-rich water would be specified outside the pyramid, as beverages other than milk don't tend to be included.
Note: I probably also would include a note with my pyramid that some "cheating" by eating some cooked foods and foods outside this pyramid is probably not going to cause serious harm to most people (though little is known about how little of a toxin from Neolithic or cooked foods it takes to start causing problems in sensitive individuals), but how much one can cheat will vary by individual. I myself sometimes eat cooked Paleo foods (like cooked fish) or even cooked Neolithic foods (like a little bit of rice or french fries at a restaurant).
