I can see Denver Broncos (#20), LA Chargers (#22) and GB Packers (#23) willing to trade up because they all need a RB and a DE in case RB Jeanty, Edge Williams or Edge Pearce are there available at #12 when the Cowboys' pick comes up. Also, because all 3 teams do have picks in the 2nd, 3rd and 4th rounds which would allow them to trade up to #12 in the 1st round.
Pittsburgh Steelers at #21 would not work because they have no 2nd round pick this year.
