The main source of complexity for this sort of thing is diffusion: bright LED lightbulbs are unpleasant to look at, and light the room in an unaesthetic way. My thought would be to build lamps you can buy in sets of four, stick in the corners, and throw as many lumens as possible onto as wide an area of ceiling as possible without the bulbs being directly visible. White paint usually has an albedo of around 0.8-0.9, so you don’t lose much on the first bounce, and it’d light the room evenly with a much simpler setup.
