At this time, no. 1.21 is meant to be very strictly close to Vanilla, as an option for those who don't enjoy 2.41's changes. Let me guess- it was Chocobos who made you want to smash your head against a wall, right?
If so, they're much rarer now and are slightly easier to put down in 2.5, which will be released sometime this week. Save files will transfer perfectly fine, just be sure that when I update it and release the new patch that you patch a clean ISO.
