I don't want the alignments to be baked in, but something like the Aasimar and Tiefling but for the Lawful Outer Planes and the Chaotic Outer Planes and the Outlands, yes.
In fact, my opinion is to do this:
Glitchling/Modron for Lawful
Plasmoid for Chaotic
Ardling for Neutral
I know Ardling was designed as Guardinal/Archon/Bauriar, but I feel like animals are more neutrally aligned (or unaligned, even), and animal head people would fit better for the Outlands and the Neutral Aligned planes in general -- so Outlands, Elysium, Hades, Mechanus, and Limbo.
Here's how I would put it:
Aasimar: Astral Sea, Arcadia, Celestia, Bytopia, Elysium, Beastlands, Arborea, Ysgard.
Tiefling: Astral Sea, Acheron, Baator, Gehanna, Hades, Carceri, Abyss, Pandemonium
Glitchling: Astral Sea, Bytopia, Celestia, Arcadia, Mechanus, Acheron, Baator
Plasmoid: Astral Sea, Beastlands, Arborea, Ysgard, Limbo, Pandemonium, Abyss, Carceri
Ardling: Outlands, Elysium, Hades, Mechanus, Limbo, Feywild, Shadowfell
Genasi: Elemental Chaos, Earth, Fire, Air, Water, Fountains of Creation, Great Conflagration, Frostfell, Swamp of Oblivion
