No, Lucci is one of the best villains if the manga, maybe even the best depending in tastes, this to say he will not simply be used to hype Zoro cause that would ruin him and that is a pity.
Think about DB Super, they brought back Frieza because he was, most likely, the best villain of the manga. They did not use him to simply hype Goku or Vegeta but gave him a status of "serious villain" again (and totally out of the blue, "I trained for 4 months", just like Oda with Crocodile) and was on oar with the heroes, even fought alongside them against the new big bad villain of the saga/s. Oda will do the same with Lucci. He is obviously weaker than G5 Luffy and most likely Zoro too, yet he will maybe get a spar with Luffy or Zoro (not going all out) with no clear winner in the end in order to hype him up, or simply shown as a still relevant character powerwise in the current events exactly how Oda did with Crocodile.
