The people who only look at the competitive side tend to ruin the fun imo. Not everything is about stats for all fans, some like using weak Pokémon who look cute, or cool. Likewise any Pokémon that hasn't evolved twice, or is a legendary can evolve.
Moving on to another Psychic/Flying Pokémon, how about an evolution for Swoobat? It's the Unova clone of Golbat so it's likely imo.
