Your idea is nice but like nezekan said it's not practical since it's a fps engine. Plus for an mmo you want as much people to play it which isn't possible with such kind of engine. Also you couldn't call it silkroad anymore. The server has to be heavily modified to sync all the exploding particles and other stuff going on.
Plus the game content is just too ugly. in silkroad it looks ok but if you use the textures and 3d models in a game engine like that it'll probably look awful.
EDIT: Unreal engine 4 ftw.
