Doesn't matter that they are closer to the original games than now. Canon dictated from the beginning, and with only a few anomalies of games contradicting this, that Samus was not quite "Amazonian" in stature. She's a 6 foot 3 inch/ 192 cm tall blond haired bombshell, that also weighs enough to go toe to toe with the absolute worst threats that the galaxy has to offer.

Admittedly as a 6'3" tall guy, I do wonder about her only being about 200 lbs, since I am about 30 pounds heavier at the same weight, but I suppose I was lighter when I was in university and the USN.

Trying to make Samus into a pixie waifu character would be like trying to make Tinkerbell into a punk pirate that followed Captain Hook, or trying to turn Harley Quinn into a perfect conservative housewife. The ideas are literally antithetical to the original character.
