Ohhhh, that's an interesting idea you have there, Spirit! Though I have to admit that I've got...way too little experience to give and actual opinion or be any help, with both Pokemon Conquest (given I've never played or looked deeper into that game so far) and DnD (I've not yet played that directly, but have played Pathfinder in-person with a group of a game store in the nearest big town). From what I can tell I'd imagine it somewhat difficult of play the latter via play-by-post in a/this forum - not impossible, but in need of some adjustments, specific rules and maybe changes to make it feasible.

Setting-wise I'd lean into option No.3 (feudal Japan), as the other two feel either overused or not that appealing to me personally.
