Rank up for Variant Chapter 3 exploration

I’m just about to finish up chapter 2 exploration and looking at taking Hype, Corvus, or Quake to 4/55 to help with chapter 3 exploration. Looking for opinions on who will help me most for paths/matchups that wouldn’t be quite covered with my other 4/55+ champs. My AQ/AW attack/defense teams are set right now and I have plenty of t2a at the moment, so I’m solely concerned with Variant chapter 3 for this particular rank up. Here are screenshots of my science/cosmic rosters. Unfortunately, I have a big hole in the fact that I don’t have Gulk yet, even as a 4*.
