Yeah that would be nice. I think a lot of players do some of what you propose already, although colorspace changing still seems to be a tricky issue, particularly on media streamers.
In an ideal world, setting colorspace to 4:2:0 should work properly for all BD players with BD content. However, as an example, my Dune Smart H1 and Pioneer 62FD (aka BDP-450) players seem to apply an extra unnecessary color conversion even when output is set to 4:2:0. The Chroma Multiburst pattern in the Spears and Munsil HD Benchmark 2nd Edition disc have one of the multiburst patterns come out completely black instead of vertical strips of 1 pixel-wide red and blue lines! The chroma upscaling (4:2:0) is horrific. I have to force the output on both players to RGB to see anything, and on the 62FD the bars are half or one quarter their brightness, which points to a double colorspace conversion error happening. And this doesn't include the error my projector (Benq W5000) introduces that also has a chroma error - double wide vertical lines for red and blue!
I strongly suggest you get the S&M 2nd Edition disc and check that there is no error being introduced. Although, you may still opt to use 4:2:0 output. You can also check out the spears and munsil website (I can't recall the exact URL right now) and see if your player has been reviewed by them - then you may not need to get the disc!
Other notes: My Pioneer BDP-62FD has dual HDMI outputs. The second output, labelled HDMI SUB, does less processing in the video. However, it does Nearest Neighbor chroma upscaling, so the chroma multiburst pattern results in double-wide blue and red vertical lines (according to the link in my previous post, this can result in contouring in some cases). But at least it doesn't add a mild edge enhancement that the other output adds. And this is with RGB output. 4:2:0 and 4:4:4 YCbCr is still incorrect on this player! ugh!
