With those logistics I reckon weight is going to override all other concerns, considerably. Dried, powdered, minimal packaging, premixed ingredients. Other polar food plans may not really be applicable, as they often take butter and/or oil and other relatively heavy things, plus a lot of fuel to melt snow for water. But I guess you are low down, not up high on the plateau, so high fat calories and water should not be issues?
50 days food should be at least = 60kg each.
150ml fuel pppday @ 50 days = 7.5kg each
Climbing gear and cameras etc = max 15kg each?
Tent share, sleeping gear, bits & pieces = 5kg each? Total 90kg.
Call it 85kg each to get from coast to camp, leaving 5kg food behind at the coast as emergency.
First trip is route finding and shakedown with 25kg load for 2 days, then 1 day back
Second trip is easier, 30kg for 2 days, then 1 day back
Third trip you go it 30kg(!!) in one day. Rest.
You've used up 8 days food already
30kg loads over boulders is bloody hard work, so you'll need the calories but not want to carry them. Be wary of taking heavy stuff from home that is nice, or high calorie, but when the carry comes you decide to leave it behind, saving weight but losing calories.
Invest in going around buying different freeze-dried meals and test them. It's worth it for 50 days to not have to eat stuff you hate. Everyone has different tastes and peoples' preferences change in the cold, weeks out, starved of other things. People usually take too much chocolate and sweets and not enough savoury tasty things. Drink powders vary widely in the amount needed to make it how it should be, so check and compare
