Thank you
I wanna note that when I make fakemon, in the process I also imagine how it would be obtained, what kind of area its found in etc. I mean when I was making myoto pokemon for example, even the dex order, levels of evolution and move learning, I put thought into those so they would fit into my made up myoto region of a nonexisting game.
You can try spriting them if people can find my art from the result no problem.
As for using them in a hack, I would be okay if you used some of them as normal wild pokemon (like how some Johto pokes (Noctowl, Wooper, Marill..) are found in Sinnoh too) , but wouldn't want to see it being filled with mostly Myoto pokes, and especially not the important ones being presented as native to Anbuja, I mean starters and legendaries.
It would be another story if I was making fakemon specificaly for a team project like yours, but I take reeeaaally long to even make just art for my own made up regions, because I take it all way too serious and think too much and remake everything so often. The 100 Myoto pokemon for example took me past 3 years and I even had quite lot of time for this.
