Widescreen hack possible? Any volunteers?

The main things to change that I can think of are the following:

1) Render the tilemap outside the regular screen size (same for overworld maps and Airship mode)
2) Manage NPC movements outside the regular screen size
3) Change some maps tilemap that would look quite ugly on widescreen (Narshe in mind as an example)
4) Adapt main menus to widescreen

It's possible to do these things I think if I understand correctly how widescreen hacks work, but it's probably a huge project to tackle..

#1 this is the most important job. Just rendering scrollable areas further, uncramping the view distance during exploration. Mode7 airship stuff won't need any hacking, it's widescreen already.
#2 the thing that really matters here is to make sure the npc sprites are visible and not "popping in and out" of some invisible threshold. There is a "sprite unsafe" option that helps with this. Anything else, like keeping them moving, is gravy.
#3 I think it's best to avoid subjective alterations to the maps. If there's garbage tiles on the edge that were previously hidden, sure blank them out, but I wouldn't rearrange anything or do landscaping.
#4 the only thing that needs done here is to prevent the menus from repeating into the expanded area. They don't need to be widened, because the width is not fixed anymore. For example, 384x216 and 448x224 are both going to be options. If a hacker widens menus to 448, they're going to be cut off in 384. Battle backgrounds can't be widened or repeated either, so it's best to just keep these elements at 256.
