I ended up making my own patch with some of the changes mentioned above and some others.
I can't make a post anywhere else, but here it is in case anyone is interested: ups patch on a clean US ROM.
FE7 Reversion Patch by Gaggle of Geese (all credit) is applied.
The "Gate" and "Throne" terrain types grant 30 Avoid instead of 20.
The "Gate," "Castle Gate," and "Throne" terrain types grant 3 Defense instead of 2.
The effective damage multiplier was raised from 2 to 3 for Aureola and all non dragon-slaying weapons.
Bosses that had their stats reduced in the U.S. version of the game have had them restored to their Japanese stats.
In Chapter 27: Cog of Destiny, Lloyd and Linus each carry a Runesword rather than a Light Brand.
In the first part of Final Chapter: Light, two doors open at the start of the map, after which two doors open every two turns. (By contrast, the U.S. version starts with one door open, and one door opens each turn.)
The Fire Dragon's max stats have been increased (even though they don't hit those caps).
Some enemies have had their inventories tweaked to match the Japanese version. (There were only four of these.)
