That's a very good question! I am guessing that the memory addressing might be tricky to figure out - again, I wouldn't be surprised if repair shots had tried it. It's always safer to use the hardware parts with most compatible specs - similar like how people do hackintosh [1] :) You have to also consider the memory chip availability at that specific size and BGA packaging - since Apple is a top consumer of those flash memory chips with only 32GB, 64GB and 128GB in sizes (omitting 8GB/16GB), the production of of those memory chips might very well be coming in ONLY those sizes due to the economies of scale in manufacturing cost.
