Can't hurt to try it...
However, in my past experience the Geo lod's don't work like they should if they are too complex.
An example is the EC's Kilo Class Submarine. We left it unbinarized so I suggest you download it and have a look! (get it at our site, a link is in my sig)
With our submarine, you need to keep in mind that the geo lod doesn't match up with the other lod's like other addons. This is because of some workarounds we did to get the sub to work, but you can still see the geo lod and compare it to the others.
When you look at the geo lod you'll notice that it's two simple shapes instead of a lot.
Let me know if looking at that helps you.
