Now that Barbosa is out for the season we could use another guy similar to him. Also we still need a big man. So how about going after disgruntled big man Chris Kaman and Rodrigue Beaubois? We could get rid of bass but move Melo and Collins and a pick to seal the deal.
Dallas is going nowhere this season. Could use another pick and they could use that pick to deal bass in the off-season to sure up some cap space.
Your reasoning makes sense the only problem is, Dallas wants to save cap space for this upcoming summer, both Kaman and Roddy are expiring deals so this would hurt them cap wise.
