Check "Has Distant LOD" in the http://www.creationkit.com/Static. Then http://www.creationkit.com/Distant_LOD_Meshes_Dialog to associate it to.
Depending on what statics you used there might be LOD meshes/textures already available or you may have to create them yourself.
I think that's only used when generating LOD, meaning it wont do anything if he never actually re-generates LOD for the Tamriel worldspace.
The issue with that is who the heck knows what else you're overriding and what other issues you're creating.
I think the Fallouts had a command specifically for 'Generate this cell's LOD' or something, but they seem to have taken that out. So, I'm not sure what you can do...
