I have posted updates to Aesthetics and Fusion that improve mod compatibility with other mods that provide copper, tin, bronze and steel ingots, namely "Thermal Foundation" and "Immersive Engineering". Basically, if you have either of those two mods installed, and don't care about mythril, adamantium, onyx, or fusion alloys thereof, you don't need Simple Ores installed, and/or can use the other mod's ingots to make stuff in Aesthetics and Fusion. This has not been extensively tested (hence beta), but I have successfully tested making Fusion bronze ingots in the Fusion Furnace using Thermal copper and tin ingots. You will probably have to manually enable the items and blocks you want in the config file, because the default config setups for Fusion and Aesthetics disable copper and tin stuff if SimpleOres is not loaded, and disable bronze and steel things if Fusion is not loaded.
For other mods not named above, you'll have to make sure the other mod loads before Fusion and/or Aesthetics, or the "foreign" ingots will not be detected. Obviously, this only works with mods that bother to use the ore dictionary for their common metals, but as far as I know, most 1.12.2 mods do so.
There was also a fix to doors in Aesthetics--I fixed a bug that prevented copper and tin doors from having configurations, and thus, prevented them from existing.
