Yea, the more I think about this the more I just don't see a way that a KD trade solves the Suns' problems without simultaneously exacerbating their depth and age issues.
Chris is already at an age which demands "load management" considerations, and sacrificing the Suns' wing depth to assemble a big 3 two of whom are in their mid-to-late 30s just doesn't feel like a recipe for deep playoff success.
Someone mentioned it on a podcast--perhaps Nate Duncan or John Hollinger--but the era of grabbing 3 stars and filling in around them with minimum guys feels less and less doable given how much the style of play has evolved in the last 5-10 years. Way more possessions, much more off-ball movement, much faster pace, more ball movement, etc. Chris is already at an age where he really doesn't guard the other team's point guard as his primary assignment, and that trajectory is only going to escalate from here on out as he continues to age.
