USB isn't just 5V, PPS actually lets you request a specific voltage and current, so you wouldn't need driver electronics at all in the actual light, as long as all you want is just regular on/off control, so the light part can be just a bare LED and a communication chip.

A socket adapter might be the best for getting it out there though, you'd need more new electronics but no new construction work. But with a new electrical interface you could cover RGBW too.

I wonder if it would be possible to make the heat sink a separate part too without needing paste or degrading performance, since heatsinks don't wear out
