Couple things -- Tito has not been removed from the UFC Hall of Fame. However, for me, when my UFC page is set to Canada it doesnt show him, Forrest or Bonnar (the 3 most recent adds).
Anyways 5 additions:
1. John McCarthy -- in the early Zuffa days was just as synonymous with the UFC as Buffer and co. Also revolutionary in terms of teaching rules
2. Rich Franklin -- Former UFC MW Champ, fought basically everyone at 185 and 205 including: Machida, Anderson, Hendo, Wanderlei, Forrest, Chuck, Cung, Shamrock, Tanner. Being a teacher also helped bring the sport some respectability
3. BJ Penn -- Former WW and LW champ, the most dominant UFC LW, one of only 2 dual division champs. Part of the only true Champ vs Champ fight, on list for most title fights, and most time in octagon
4. Anderson Silva -- former MW champ, most title defences, most consecutive UFC wins, most KONs, 3rd most title fights. Candidate for best fighter ever.
5. Georges St Pierre -- former WW champ, most title wins, UFC wins, most consecutive rounds won, second longest winning streak, biggest star produced by Zuffa.
I would add Anderson and GSP now as both are unlikely to ever fight for titles again. Also due to their dominance, along with BJ, all 3 should not have to wait for their retirement for induction
