One of the things keeping me from doing so is the fact I can already get over 100 Ingots from one ruin's worth of scraps, which is a significant increase in Smithing skill as it is.
Not really; seeing as you can't make anything from dwemer metal without adding at least one iron ingot, it wouldn't actually allow the production of more of the small items commonly used for grinding up smithing.
If you are just referring to the profit from the sale of ingots, that has no effect / need for the Smithing skill. It would be more of a potential impact on the Speech skill.
But in any case, dwemer items are so fraking heavy you can't bring that many out of a ruins anyhow.
I do find it interesting that we don't have a 'recipe' for dwarven ingots from ore.
The recipe went away with the dwemer. It probably can't be produce from ore in a smelter anyhow. As a real world example, Aluminum ore can't be refined with heat alone; it requires and electrical or chemical process. Or it may be an alloy that requires a small amount of a metal not found in Skyrim. A real world example of that is stainless steel, which requires Chromium, which is only mined in a very few places in the world (mostly South Africa).
