Eh, I am not sure if I would describe Pace as having a shotgun approach. IMO, he tries to cover all the immediate needs in free agency so that he can try to stay true to his board and draft BPA.
When I think to the example of drafting 2 ILB's last year, the argument can be made that those were BPA picks. Certainly, Roquan was considered a BPA pick at #8. And the athletic traits of Iggy made sense in the 4th. In those middle rounds you are just trying to find depth and special teams contributions that can be developed into a starter someday.
Now, the kicker situation is certainly more of a shotgun approach. But he has screwed that position up so much that he basically has to do that now to try and find one that works.
Similar to kicker, the Bears wide receiver position was seriously in bad shape. It was not so much a shotgun approach as acknowledging that nearly their entire wr corps needed to be replaced. Think back to 2017 and remember for most of the season after the Meredith and White injuries that the WRs were guys like: Kendall Wright, Deonte Thompson, Tre McBride, Dontrelle Inman, Tanner Gentry, and Josh Bellamy. Of that entire group including the injured guys, only Gentry is still around on the practice squad. They probably would have liked to hang onto Bellamy for his special teams work and he was actually get better as a receiver with great speed, but he was too expensive in FA. The rest were let go for good reasons.
So, that was a long winded way of saying that I expect Pace to stick to BPA and build depth. I would think that he takes a RB at some point and if his BPA says to take 2 RB, then so be it. But, I think in that instance he would probably try to move around in the draft to match BPA to need and avoid doubling up at RB in this particular draft.
