Not sure what sort of home console would be possible today with carts and passive cooling. Probably just a non portable version of the switch.
20~ 20 Watts would be just about doable with a large enough chip and a big and well ventilated enough heatsink, at a guess.
Sooooo in other words, about 1/2 an X1S on 16nm, in huge audio amp separate style box.
In other words .... no.
