@Broozar: Modo can read and write LWO's directly. I tried the trial to check this out. Modo can also read/write UVMaps, MorphMaps and Weightmaps (and other Vertexmaps) from/to Lightwave.
I think that the Lightwave-Modo-Combo is a real timesaver because you have a seamless workflow. A good File I/O-Support is an invaluable advantage.

I did not know that you only use Layout.
Unfortunately i dont have the money to buy Modo. So i have to wait.
