Just found out that the pickup graphic for the BFG2704 was finished at some point after the 0.5 alpha, and that the pistol pickup graphic I've seen in UDB wasn't custom either. There was also a Berserk Stim at one point (though it could be an alternate graphic for the Beserk pack). It makes me wonder if the view sprites of the missile launcher were completed; if the 2704 had a view sprite (or view sprites) made before being replaced by the 9000, if the Dark Claw had view sprites made before being scrapped, and how a Berserk Stim would've functioned (heh, maybe it would've worked how the Berserk pack was supposed to).
