Doubtful. They know that would result in fans burning down their offices.
For all the worry of cutting shit down, people forget FF7 is actually super fucking thin on content. Most of it's length comes from random battles and reading. There aren't many locations with a lot of time spent in them. Midgar is one of them, Junon is another, and that's really about it, unless you count the Highwind itself. Most of the cities you go to in 7 only really have you there for one or two plot points, not counting return trips.
Kalm just has the flashback, you stop by the chocobo ranch to get the materia, Costa Del Sol has you talking to Hojo sunning himself in a lab coat, corel has racial hate and another flash-back.
Even if they take the time to flesh these places out, there's not a lot, plotwise, you can do there, so it's not unthinkable to wrap up an entire disc and a half in a single game.
