The rules are also in the apocalypse 2 book, and there are several loadouts. This means that there could be more weapon configs coming out at some point, but there is nothing to say you can't do weapon swaps for yourself. I have 4 as I like the miniature, working in 2 pairs. They do a good job, for me in a mostly suit army lead by Rymer.
Go ahead if you want your own special character, just make sure to tell your opponant what weapons it's carrying if not immidiately clear.
Good Luck
