Here's a novel idea: leave it alone, the original is fine the way it is. If it's not broke, don't fix it. This is like someone attempting to re-do the guitar solo on Freebird. Ugh.
the purpose of a romhack is to change stuff that the author didn't like.
it'd be like those easy hacks where all that's done is some slight graphic replacements, but everything else's left the same, so there's little to no new experience.
