Just a quick glance indicates that you may get better airflow by having the inlet toward the body and exhausting over where you have the bottle in your diagram - just a gut feeling. Either way you go, maximize the body to condensing coil distance, since you essentially have a "wall to wall" interface there, and getting air flow to the center of the coils would be of your major concern.
Please post pics of your progress. A friend of mine has a split LG unit in his spa room and he thinks it is the best thing since sliced bread.
