Dave I would have to say that it is not a good idea. The chain needs be dry so nothing sticks to it all all.
WD40 contains about half it's volume of Stoddart solvent aka white spirit!
The roller in the chain is surrounded by a lubricant which is sealed in by the 'X' ring - a 4 point of contact seal.
If you spray on WD40 (which stands for Water Dispersant batch 40!) the solvent will dry out this seal and damage it, possibly after repeated use perishing it and that will lead to the inner lube leaking out damaging the chain & sprockets even more.
Chain lube of anykind will not 'fling everything off' in sand even if you increase the flow (even if it sprays your wheel) but offer a material that will combine with fine, almost dust like sand particles as well as large ones and form a grinding paste.
This damages the chain, front and rear sprockets increasing wear on all 3.
When you are finished with sand riding, then give your chain a good clean and turn on the Scot-oiler or the like for road running.
