The Bengals would get a top 4 Lt who's actually on a good deal. with this+ a Lael collins trade they could have Tunsil, Cappa, Karras, Collins, Williams.

Texans would get picks 31, and 63, 126. Bengals get pick 45

I think Tunsils value is right around a first, but the Bengals would also enjoy still owing a high selection so they would tack on their 2nd and 4th to get pick 45.
