Which classic Ratchet and Clank Planets should be in Rift Apart ?

[npzman]

So in the upcoming game Ratchet and Clank : Rift Apart there is some planets from previous Ratchet and Clank games that's making a comeback in Rivet's dimension and with Ratchet and Clank 2016 not having every single planet from the Original 2002 Ratchet and Clank game. There is a chance that some missing planets might make it's way to Rift Apart.

I thought they were gonna just bring back planets from the Polaris Galaxy only. But then it's speculated that Koros from Ratchet and Clank : Up your Arsenal (Ratchet 3) is going to be on Rift Apart and that planet is from the Solana Galaxy. I'd love to see some planets from the PS2 games make it's way to Rift Apart. Which planet from any Ratchet game would you like to see in Rift Apart ?
