That was a joke right?
A lighting tree will hold up the same amount of weight on the playa as it will in defaultia. What you've got to be worried about is wind. LX trees tend to be more of an indoor solution and as such don't have any way of anchoring them built in. VC is right that guy lines could help but that is going to look messy and create trip hazards. If LX gear is somehow easy to come by for you I'd recommend a stick of truss on a base plate like this;
Then rather than a top heavy upright guyed to the ground you have a fairly bottom heavy structure, assuming you're only hanging fabric. You could improve things with rebar or lagscrews through the extra holes in the base (there's usually holes) or by stacking heavy stuff on the plate, big jugs of water are the usual trick.
But really for fabric banners this is overkill. You could easily knock up a custom frame out of wood that will look better and likely be cheaper. Plus then you avoid the ire of the lighting hire company when you bring back their gear covered in dust, which for the trees would be even more annoying than the truss since they have moving parts.
Hope that helps.
