I want to create a Sea bird fan evolution line is it Good?

I want to make fakeDigimons and I saw that there's not much bird digmons so I wanted to make a Sea bird based line

Let's start with a Rookie I thought of the seagulls.

So i Thought of a name, Gullmon.

Then For it's champion it would evolve into Albatrossmon Wich Is a bigger Sea bird to Fit with the Acuatic bird line.

For it's ultimate it would evolve into Pelicamon as as you guess Big Pelican monster that Fires high pressure Water from its mouth.

And for it's mega Evolution it evolves into Pelagornismon a Big ferocious and ancient Prehistoric Sea bird who is the Sovereign of the Seas.
