My ideas:
1. El Paranormal Tales of Rainer (Gravity Falls with a Latino Cast; set in a fictionalized version of Seattle)
2. BirdMyths (DuckTales with different kinds of Birds)
3. Voltechnus (Voltes V + Phineas Flynn from PnF as Iron Man with a Tron vibe)
4. Johnny and Mack (A typical Teen Comedy series).
