Doing this a Leathery Dragon would make 454/min, a Cotton Dragon would make 447/min, a Paper Dragon would make 459/min, and a Panlong Dragon would make 403/min. All at level 20 with cold, fire, earth, water, plant, air, and lightning boosts on the island. That's 1763/min. An Aurora Dragon earns 480/min (x2=960) and a Double Rainbow Dragon earns 499/min (x2=998). That's 1958/min. A considerable 195 more per minute. If you have four Double Rainbow Dragons you could earn 1996/min, 38 more per minute than the Aurora/DRD combo and 233 more than the hybrid combo.

Based on the figures I just did, I would keep your 2 Aurora / 2 DRD combo to maximize coin efficiency in the Omnitat.
