This is what I think should happen: With SANADA injured and possibly going, and EVIL likely going. Here is what happen. My ideas also suggests not keeping Fale or Chase Owens for both.
Option 1: Make it the new Suzuki-gun. More so late stage Suzuki-gun where they were heels, but less so cheating, but more so relished in causing pain in ring, and thinking they were above everyone with better technique and that. At the very least less. Ren Narita would be the new head of this faction, he would embody this well. Possibly turning on Yujiro. Maybe bring in Boltin Oleg for this group, he could be jealous that Aaron Wolf is getting the star treatment now, so he could tag with Ren, and try maybe to bring someone new to the company who could fit this, maybe Tommaso Ciampa for a foreign talent, he could fit given his previous persona even if he is a bit on the small side.
Maybe Young Guns, or Cowboy Way from the indies, or possibly LaBron Kozone. Hard to say what wrestlers could jump from different Japanese companies, it is a fair bit rarer, but could be good, a freelancer like Shinya Aoki would work for a bit, dream would be Katsuhiko Nakajima but he seems to be going back to NOAH, Takanori Ito or Ryo Aitaka from GLEAT would be cool.
Option 2: Have them lose a big match, Tanahashi can say that now he is retired he has more time to focus on his presidency and that he has come to the decision to fire EVIL for such agregious and constant cheating, and the rest will have to return to to young lion status to keep their jobs. Yujiro could struggle, eventually be a hontai pin eater. Douki and SHO could do it for a tour and 'leave for CMLL' work there for a bit, and win the NJPW Strong Tag Titles off Angel De Oro & Niebla Roja use that as leverage to come back as heels (probs kill the Strong belts soon after), but less cheating ones. Not sure about Kanemaru and Togo, probs have them do it and not care. For Ren Narita I would have him absolutely slaughter the young lions and be rebranded as a junior heavyweight for over a year. Be put in the BOSJ, lose in the finals, but challenge the Jr Champ and win it later. Then about a year later he would win BOSJ but challenge for the NEVER Openweight Title and win it, and he would graduate back to heavyweight after the reign.
How would others tackle this change up
