Trading a player acquired with the DPE

[stes]

Hi everyone,
If the Celtics were granted the DPE for Hayward's injury and used it in a trade (for let's say J.Okafor or B.Portis), would it be possible to use said player in a trade before the deadline after waiting a standard 30-day ban)? It seems like it should be prohibited, but maybe it's a loophole. And if there's a GM in the Association that could get creative like that, it's Ainge. 
I was searching the web, but couldn't stumble upon an answer to this question, so I decided to create my first cb topic. The idea behind a question is rather specific, so unfortunately I won't generate much of a discussion. However I am not an active twitter user and a lecture of CBA FAQ didn't lead me to any conclusion, so you are my best option to clearing my mind.
