What if X studio made X game instead?

What would {‘Game’:‘Pokémon: HeartGold/SoulSilver’} be like if the game studio {‘Studio’:’FromSoft’} made the game instead? Can you give me an example of what the gameplay would look like? Would it be 1st person or 3rd? What genre would it be?
Do you think it works as a concept or would another studio be better suited? If so, which one and why?
