About that M10 Monochrom

I've been thinking a lot lately about getting a Leica M10 Monochrom. I know, I know, it's a bad idea. I had the Leica Q2 Monochrom and sold it. But but but! The idea is that if I consider myself a primarily black and white photographer, and I do, there's nothing better than the M10M. Except it's way too expensive for something so limited. Then I had a genius idea. What about an M10-P again? But, and here's the genius part, set up Lightroom to convert raw images to black and white on import! That way I never have to actually see each image in color and decide if I should convert it to black and white. It's darn close to shooting B&W right in the camera. Later, if I do happen to get curious, I can peek at the original color version, just in case. Ha? Ya?
