A portable and a home console are both fairly different concepts.
Trying to have a compromise of both seems impossible if you ask me, considering you'd have an extremely expensive portable that you most likely wouldn't want to risk taking around, and would need a large battery to support a home console's high specs.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
