I don't see how there is much that they really CAN do this year. Expect next year's rookie (if they keep the pick) to have exactly as much impact on the squad as Gabe Pruit had this year - and seems to me that Danny would really like to keep roster spots free (since it's pretty likely that there will may be some serviceable vets who'd like to come aboard and contribute pretty cheaply).
One thought; if they did like Hibbert (who, for all of his flaws, seems like he could be a decent backup for Perk and contribute fairly soon), think a combination of #30 and maybe BBD could move us up far enough to grab him? I don't really see too many players on the roster, other than MAYBE BBD, that Danny would be looking to trade. I just think they've ultimately got more confidence in Powe being able to consistently fill than backup-4 spot than BBD, especially since he seems to have shown that his injuries are completely behind him.
