Okay. I've got it more-or-less finished because messing with sprites more than I already have is gonna make my head spin. Some of the animations aren't perfect, but hell, they're the best I could do in about a day or so with an open source picture editor and google image search. So, without further delay....
My improved character megapack. If you're wondering why it's "Improved"...lets just say you haven't seen some of the atrocious walking animations in my old version.
Ever wanted to prowl the frozen wastes as a mutant crab? No? Well...now you can.
Download - http://dl.dropbox.com/u/71356504/A%20Valley%20Without%20Wind/Improved%20Megapack.rar
Extract the folder and place in steamapps\common\a valley without wind\RuntimeData\Texture Packs
Run the game. Under Options-> Graphics, there will be a Texture Packs Option. Select Improved Megapack from the list and click the Save button.
It replaces quite a few different characters. If you want to replace a different one with a different image, you can just rename them. But the the ones I've done are:
Boris1 - Male Swordsman (Tales of The World 3)
Boris2 - Male Thief (Tales of the World 3)
Valeria1 - Female Cleric (Tales of the World 3)
Valeria2 - Female Archer (Tales of the World 3)
Justin1 - Iron Man (Altered Megaman X Sprite)
Justin2 - War Machine (Altered Megaman X Sprite)
Melody1 - Sparkster (Rocket Knight Adventures)
Melody2 - Samus Aran in Gravity Suit (Super Metroid) ((I had more Samus sprites, but I accidentally saved over them!))
INDUSTRIAL REVOLUTION AGE:
Raya1 - X (Megaman X1)
Raya2 - Zero (Megaman X1)
Samantha1 - X in Armor (Megaman X1)

Snowsuit, Heatsuit, and Heatsuit Advanced Icons are changed to their Ride Armors, as noted above.
Most characters I added in have a new, unique ghost for their model. I forgot it for some characters (Like the crab!), but most have them. And they're a bit more intimidating-looking than the Obi-Wan-Kenobi style Ghosts the game came with.
WHEW. I think that's everything. I probably left some temp files and assorted junk in there somewhere because I wasn't paying attention, so there might be some alternate sprites and whatnot. Anyway, all credit for the sprites goes to the original designers of their respective games and whatever graphically-inclined folks ripped them out of those games. Feel free to use 'em. It really does give a different feel to the game.
