I would love to play Chocobo Hot and Cold but I'd really like to see it bound into
Chocobo Paradise / Chocobo as a content piece if possible :3
I'd take Gold Saucer implementation over nothing of course, and don't mind if it has some relations to that system (MGP rewards), but just kind of hoping chocobo's get a bit more of their own pie lol.
Regardless though Chocobo Dungeons (and hot and cold) could be a lot of fun

. Perhaps the dungeon content can be with moogles too. Are you thinking a bit like PotD/HoH? Or maybe a bit like GW2 Adventure Box game?
As a fairly large aside talking about Gold Saucer/Mini-games I wonder how hard it would be for them to make some of these mini-games
also available in their companion app.. Bet a lot more people would use/like it if they could play Triple Triad, Cactpot, Mahjong, Lords of Verminion, and more on the fly. That and I bet they could make one of those runner games with a chocobo theme and that'd be fairly loved so long as it isn't glitchy/buggy (endless swipe on screen to dodge/jump obstacles).
