From that standpoint yes but I'm only talking about the Japanese releases since the Super Famicom release of both FF2 and FFG were only a few months apart. Going by the in game story line of FF2 it heavily looks like Guy was going to be the central character until maybe Capcom decided to go in another direction like making another cheap and easy expansion like FFG. All I have is a conspiracy for now but I'm pretty sure Capcom higher ups would have tight lips on any employees that would dare speak out and they have been known to have rough relationships with designers before like Keiji Inafune.
