I don't see any problem. The HLT can be a cheap pot since it's just water, you can get a 10-12 gallon cooler reasonably and add a spigot. How much that will cost depends on how complicated a manifold you want. The chiller is a bit less flexible. Copper prices are high.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
