I was thinking the same thing..
When I was rendering my Babylon-video ( 
https://www.youtube.com/watch?v=oAckZrhGN3U , looks awfully dated now 
:)) I did something similar to decrease rendertime.
By simplifying the textures depending on distance and viewing angle, I 
didn't need that high AA settings, often resulting in render times of 
seconds instead of minutes.

It's difficult to automate the process for every kind of texture, 
though. Or rather: it's difficult to automate it while not making it 
slower than just using a higher AA setting :)
