we can open a discussion here...

first approach, just to introduce the discussion...

groups inside a LOD group
each group with bounding box/sphere
each group has some sort of minimal requirements (area of projection in 
pixels, distance from POV, minimum angle, moon phase, you name it)
and the submit loop inside the LOD group choose wich one to submit...

This Switcher group can be also handy to texture and other types of 
animation, suffice to change the criterion used to choose which 
subelement to submit...
