Good strategy but that would be really difficult at the moment. To me, the problem isn't about Final Fantasy as much as the know and how of making an RPG has change a lot in a short period. I think the most basic example of that is if i were an RPG director "what should i choose fast travels/warps or airships/cars?" To me the if i want to make an FF game i will choose airships/cars but if i want to make an "approachable" modern RPG i have to choose fast travels/warps which is much easier and less time-consuming as well.

That is without mention other stuff like the fact that modern FF is like 70% dungeons or in some cases the percentage goes to 100% like FF13. If you want to overcome FFVII you need a more uniquely detailed "locals" not a dungeon crawler with repeated textures.

I feel it is impossible to overcome the lasting impression of any old FF but you won't know without at least trying to.
