How you thought this is a W for Lanji is beyond me. With the evidence we had at the time there was no reason to believe he was in CP0. So drawing an obvious conclusion from the evidence isn't an L, it's being logical.
Next, since Kalifa, Blueno and Kumadori also made it into CP0, it isn't actually the W you think it is, if anything that's just de-hype for the entire CP0.
And Kaku/Lucci have been portrayed very distinctly from the rest of the group. They are in egghead with awakening taking on Luffy/Zoro trying to assassinate the world's leading scientific genius, whilst Jabra is with the rest of the scrubs at mariejou getting duped by Wapol.
