If we acquire 2 starters like you mention, we'd have those two, Arrieta, Jackson, Wood, Wada, Hendricks, Turner, Doubront, and Straily for a total of 10 starting pitchers. Hendricks, Straily, and Wada are the only ones that could be sent to AAA. Depth is good, you want depth. Right now we have depth, and if you add more to it(like most people want to), you're going to end up in a position where you create next year's Bonifacio by DFAing the losers in late March if you don't pare down the list a little. Wada makes a good trade candidate because he's not a good relief candidate, he's having MLB success now, and his age is such where you aren't expecting more than a couple more quality seasons from him. Keeping him is perfectly fine, but if you're adding to the rotation, somebody(or several somebodies) need to be outgoing too. But there's no reason to trade him just to trade him. If somebody were to offer a legit prospect, then yes. As for what we have, I see Arrieta as at least a legit 2-3. As for the rest, Wood could be an above average 4 starter, but also a trade candidate, leaving Turner and Doubront, who have the higher ceilings, but also lower floors. Wada and Hendricks I see as best case scenario 3-4 starters, worst case scenario, decent enough 5. As for Straily, I have my doubts that he's any more or less likely to stick in a big league rotation than Beeler, Rusin, or Rhee. With this in mind, Wada shouldn't be so much trying to earn a rotation spot next spring as other guys are working to force him out, making him a candidate to shop at the end of ST rather than winter.
