Given that the best time to have changed the names would have been when SB released I'm gonna go with no. Personally I don't mind current naming scheme myself in part because its a nice call back to what the original localization team had to do for the first Final Fantasy game (which was due to limited character space for those not in the know.)
And if we went by Fire/ra/ga/whatever they decide for the fourth since that one doesn't seem to have a set name, the same people doing this with Fire 2/3 will do the exact same because hey, it has a different name so it must also be stronger and I no longer need Fire!
