My pick would be Verse, but I can see where you are coming from. I think taking Verse at 9 would have the Bears getting a step closer to the defense becoming elite.
Using the Packers as an example really is proof that you don't have to use 1st round picks on WR's. Reed, Watson, Musgrave all 2nd round picks. Doubs 4th round, Wicks 5th round. Most of their first round picks have been on defense the past few years.
Bears have Moore, Allen, Kmet, Everett. Then there is Scott who I am not giving up on with a more accurate QB in Williams throwing him the ball. Also, there is still talent in the 3rd round at WR to choose from. Swift will also be a major option in the passing game that some here are overlooking.
These moves will still give Williams the kind of riches you are looking for, while making the defense that much stronger.
DE or WR at #9 Poles is still getting that blue-chip prospect he is looking for.
