Middle Evolution and Pre-Evolution Wishlist

Many moons ago, Bulbagarden user winstein posted about introducing middle evolutions. To quote him;

I am going to make a wild prediction and say that they could introduce middle evolutions. What I meant is that they introduce something that the pre-evolution will evolve into, while this Pokemon evolves into a final evolution. Basically it's like something that fills in the blank within the evolution.
There are three candidates that would fit best here: Larvesta, Rufflet and Vullaby. Their evolutions felt like there is a gap between the basic stage and the fully evolved stage, so a possible middle evolution could allow for something in between that is stronger than a basic stage, but weaker than the final stage. As a bonus, they will learn moves that could only be learned by them. If possible, the middle stage could also be different in battle style, like in the example of Vigoroth, who is very different from Slakoth and Slaking's laziness.
Thanks for reading.

With this in mind, my wishlist for such a thing would be:

1. Larvesta
2. Vullaby
3. Rufflet
4. Noibat

While the following Pokémon would work with middle evolutions, they are better with stat buffs

1. Riolu
2. Munchlax

Though personally the entire franchise needs a stat rebalancing.
