You are entirely under the assumption when I propose a certain style of remake that this vision is in line with what they have in mind, in all likelihood they would approach it differently, build everything from scratch, change most parts up and keep the basic story and characters intact and make it no longer a turn based affair.
However, if they wanted to build one leveraging their existing resources in much less time, and less cost, they COULD, but again, that depends on what they want the resulting remake to be, a true to the original copy or a ground up rebuild, if there's one thing square are notorious for its rebuilding rather than using perfectly viable assets.
That however does not detract from my point of them having enough resources in their archives to greatly reduce the cost of developing a game that uses them, so pointing to them saying it would cost a lot when they're looking at it from a point of a completely from scratch remake doesn't take any of that in to account.
If you get any future employees be sure to send them my way, you would be surprised by just how many places this "nobody" could take them behind the scenes of the industry.
