It depends on the quality of trade offers. Generally, it's better not to panic trade but if the right trade comes along, one has to look at it. If such an offer came along, it could create a domino effect of other trades.
Looking at the other side of the coin, if the Suns could trade for Butler and add a center without seriously mortgaging their future, it might be worth a shot. However, it has to happen soon or another season goes into the dumpster. Since the Suns don't control their future draft picks, it's less risky. The Suns are already paying Beal a huge salary.
