Could Hippogriffomon and Gryphonmon be possible later forms for Penguinmon?

HippoGryphomon is already part of Darcmon's line of evolution and Gryphomon is usually treated as being Deramon's next form.

And taking into consideration Penguinmon is unable to fly and has much more alignment with ice, I think it is more likely for him to evolve into something like a marine or artic Digimon, and not a flier.
