For now I don't have plans for evolutions, due to the possibility of having inconsistent LORAs generations, and have to take care of each possible evolution chain. For example, caterpie to butterfree, there's not much LORA for caterpie and metapod, so it's a bit difficult to include them.
But with that said, adding flareon, vaporeon (Heavy favorites (wink wink)), jolteon and other Eevee evolutions won't be an issue, because their high quality LORAs are easy to obtain.
