Combining plant protein sources doesn't actually increase the protein content so much as reduce the protein requirement, by matching the ratio of amino acids consumed more closely to the essential amino acid requirement.
One thing this leaves out is that there are certain amino acids that are conditionally essential that are never in plants. With I.V. feeding people (especially babies) can develop a taurine deficiency, as an example. And vegans tend to have lower levels of creatine.
If I was going to get most of my protein from plants, I'd probably skip the grains and just go with beans, they're high enough in protein that you can make up for the limiting amino acids by just eating slightly more.

Thanks, Professor. I knew I could depend on you. Thing is that poor people have grown and thrived on corn, rice and beans for centuries. I realize it is supplemented with meat, but the really poor don't get it that often. In Asia, the poor eat rice and fish and thrive. There must be something inside us that takes the food ingested and makes it work to the body's advantage. Otherwise the population would be much smaller, starved out of existence.
Have you heard of the Dutch Famin Cohort Study?
Toward the end of World War II, Germany starved the Netherlands. It was called the Hunger Winter; something like twenty thousand people died. As you’d expect, the women who were pregnant at the time gave birth to weaker babies. That part makes sense. But the surprise is that those children eventually gave birth to kids with the same problems. And so did their kids. Study of that is epigenetics.

The Dutch Famine Birth Cohort Study is an ongoing study investigating the effects of exposure to the 1944-1945 famine in utero on health in adulthood. The study has shown that the offspring of mothers who were pregnant during the famine have more diabetes. People exposed to famine during mid gestation develop more obstructive pulmonary disease and microalbuminuria. Those who were exposed early gestation have more atherogenic lipid profile, altered clotting, more obesity, and a 3-fold increase in cardiovascular disease.

Mothers pass changes to their offspring. The DNA doesn't actually change, but it changes the way the genes express themselves, the way they’re regulated. I'm thinking that works regionally with nutritional adaptation. "This is what we're going to get to eat, so we'll make do." When people from that region eat Westernized junk diets, they get fat and sick. Just a theory.
