If you have something like PAKScape, I believe that filefront has JA mods has a download for this. I've got a few dozen blade mods like that, they work just fine in the menu in Multiplayer but for singleplayer you have to manually enter in the console command below, using one of my mods as an example.
Also, some mods only work for miltiplayer, and some only work for singleplayer, and then there are some MP things like weaponpacks that you do not by default have access to in the saber select menu the game provides. Incarnido, did you check the Readme files? There might be console commands required to activate them that are provided in the readmes.
