I've been down this road, having gone from SDD3 to 2x to 1x. I've had these debates with myself for years. It's a well trodden path.
seems like you’ve done the work for us! A modern 1x11 provides the needed gears and is cheaper, lighter and easier to service than a dual drive or even a high end IGH - thanks! Until the gearbox, pinion driven folders come out, yours may well be the ideal setup then.
