Reserve strikers Antonio Di Natale, Giampaolo Pazzini and Fabio Quagliarella hope to start against New Zealand on Sunday when a switch from 4-2-3-1 to 4-4-2 is possible.
Alberto Gilardino and Vincenzo Iaquinta, both in the 2006 World Cup-winning squad, struggled to manage a shot in the Group F opener against Paraguay with wideman Simone Pepe the driving force.
But while Italy's misfiring strikers undermined the team's performance in Monday's 1-1 draw, the problem for Lippi is that his remaining candidates are far from household names.
"We do have very strong forwards but what counts is to have a group that works together, maybe that's more important than having a really top player," Pepe told reporters on Wednesday.
Juventus forward Del Piero, 35, can still be deadly with free kicks and little passes even if his powers have waned while AC Roma's Totti continues to conjure goals from nothing.
"With Totti we are talking about a champion, an absolute champion but let's not talk about who is missing," Pepe added. "There are players of quality here."
"I've learnt to cut inside and have more shots. Being on the left or the right for me doesn't change anything. I must improve with my finishing, I must be more incisive," added Pepe, who is backing former Udinese team mate Di Natale to shine.
"He has often been decisive even for Italy. I've seen him do impossible things."
