I'd like to see Wilder face someone who has good inside fighing skills. I know Wilder keeps avoiding Povetkin and Ruiz Jr, so its very unlikely Wilder would put his fragile mandible to test anytime soon.
Deontay has never fought a good inside fighter. Tyson Fury is a good inside fighter. 6'9", 280lbs of gypsy inside fightingness.
The real question: Has Deontay Wilder ever fought against any type of good fighter. Your question makes it sounds like Deontay already weathered all types of masterful opposition and now just needs to fight against a good inside fighter. All his opponents outside of Stiverne were a bunch of Boxrec 30-75'ers. They were fringe contenders at best.
Stiverne is old, fat, slow footed sloppy puncher, who was dehydrated and ill in the fight night. Plus he got KTFO'd by Demetrece King and dropped by Rossy.
Has Deontay ever fought a good come-forward brawler? No. Has Deontay ever fought a good counter puncher? Except for Stiverne, no. Has Deontay ever fought a good outside fighter with a solid jab? No. Has Deontay ever fought a good inside fighter? No.
