Mutually immiscible liquids How many mutually immiscible liquids can be stored in a glass bottle at S.T.P.?

According to


  PATTLE, R. E. (1950). Systems of Mutually Immiscible Liquid Layers. Nature, 165(4188), 203–204. 


a system of 6 immiscible phases can be formed (including mercury), but the ammonia layer disappears after a month. They suggest gallium could add another layer, giving:


ammonia solution
isobutyl alcohol
liquid paraffin
potassium carbonate solution
methylene iodide    
gallium
mercury


Could silicone oil and fluorocarbons create additional stable layers, and have there been any other systems suggested since 1950? I saw a 2006 reference with allegedly 8 phases.
Better than gallium, could the alloy Galistan be used? It’s a mixture of Gallium, indium and tin. Other liquids like Bromine, Cesium and NaK might have some potential but may just react explosively.
