i dont think thickness or viscosity are what you want if you want to increase thermal capacity. by volume, liquid water on its own just rocks. its even better than solid metal by volume. and i found a few sources that say that salt water has a lower heat capacity compared to fresh water, so while the salt will make it heavier, it makes heat capacity worse, because it decreases the amount of possible hydrogen bonds between the water molecules. so i doubt solving anything in the water will make it better at storing heat. i may be wrong, but i dont see what could do the job.
